Abstract
Systems and methodologies are described that facilitate use of power and phase coherence to multiplex or manage interference in a wireless communication environment. In accordance with various aspects set forth herein, systems and/or methods are provided that receive a spectrum of tones that include additional data, ascertain whether or not tone intensities of received tones included in the spectrum of tones exceeds a threshold, based on whether or not the tone intensities of the received tones exceed the threshold, decode information included in the received tones to extract the additional data, and thereafter decode information included in one or more remaining tones that fail to exceed the threshold in order to extract primary data.

A method that effectuates use of power and phase coherence to multiplex or manage interference in a wireless communication environment, comprising:
- receiving a spectrum of tones that include additional data;
- ascertaining whether a tone intensity of a received tone included in the spectrum of tones exceeds a threshold, wherein a tone intensity that exceeds the threshold indicates inclusion of additional information that overwrites a tone initially encoded to carry primary data;
- based at least in part on whether the tone intensity of the received tone exceeds the threshold, decoding information included in the received tone to extract the additional data;
- and
- decoding information included in one or more remaining tones that fail to exceed the threshold to extract primary data.
A wireless communications apparatus, comprising:
- a memory that retains instructions related to
- acquiring a spectrum of tones that include additional data, determining whether a tone intensity of a received tone included in the spectrum of tones exceeds a threshold wherein a tone intensity that exceeds the threshold indicates inclusion of additional information that overwrites a tone initially encoded to carry primary data, based at least in part on the determining, extracting the additional information included in the received tone, and extracting primary data included on one or more remaining tones that fail to exceed the threshold;
- and
- a processor, coupled to the memory, configured to execute the instructions retained in the memory.
A wireless communications apparatus that effectuates use of power and phase coherence to multiplex or manage interference in a wireless communication environment, comprising:
- means for receiving a spectrum of tones that include additional data;
- means for ascertaining whether a tone intensity of a received tone included in the spectrum of tones exceeds a threshold, wherein a tone intensity that exceeds the threshold indicates inclusion of additional information that overwrites a tone encoded to convey primary data;
- means for decoding information included in the received tone to extract the additional data based at least in part on whether the tone intensity of the received tone exceeds the threshold;
- and
- means for extracting primary data on one or more remaining tones that fail to exceed the threshold.
A computer program product, comprising:
- a non-transitory computer-readable medium comprising:
- code for obtaining a spectrum of tones that include additional data;
- code for ascertaining whether a tone intensity of a received tone associated with the additional data exceeds a threshold, wherein a tone intensity that exceeds the threshold indicates inclusion of additional information that overwrites a tone encoded to convey primary data;
- code for extracting the additional data from the received tone with the tone intensity that exceeds the threshold;
- and
- code for extracting primary data for the received tone that fails to exceed the threshold.
A wireless communications apparatus, comprising:
- a processor configured to:
- receive a spectrum of tones that include additional data;
- determine whether a tone intensity of a received tone included in the spectrum of tones markedly surpasses a threshold, wherein a tone intensity that exceeds the threshold indicates inclusion of additional information that overwrites a tone encoded to convey primary data;
- extract additional data included in the received tone based at least in part on whether the tone intensity of the received tone exceeds the threshold;
- and
- extract primary data included in the received tone that fails to exceed the threshold.
A method that effectuates use of power and phase coherence to multiplex or manage interference in a wireless communication environment, comprising:
- randomly selecting one or more tones on which to convey additional data;
- encoding primary data across a spectrum of tones;
- encoding the additional data on the one or more randomly selected tones and artificially boosting the one or more randomly selected tones to exceed a threshold, wherein the encoding the additional data on the one or more randomly selected tones causes the primary data included in an underlying tone to be overwritten;
- and
- transmitting the spectrum of tones that includes the one or more randomly selected and artificially boosted tones.
A wireless communications apparatus, comprising:
- a memory that retains instructions related to randomly selecting one or more tones on which to convey additional data, encoding primary data across a spectrum of tones, encoding the additional data on the one or more randomly selected tones and artificially boosting the one or more randomly selected tones to exceed a threshold, and transmitting the spectrum of tones that includes the one or more randomly selected and artificially boosted tones, wherein the encoding of the additional data on the one or more randomly selected tones causes the primary data included in an underlying tone to be overwritten;
- and
- a processor, coupled to the memory, configured to execute the instructions retained in the memory.
A wireless communications apparatus that effectuates use of power and phase coherence to multiplex or manage interference in a wireless communication environment, comprising:
- means for randomly selecting one or more tones on which to convey additional data;
- means for distributing primary data across a spectrum of tones;
- means for distributing the additional data on the one or more randomly selected tones and artificially boosting the one or more randomly selected tones to exceed a threshold, wherein the means for distributing the additional data on the one or more randomly selected tones causes the primary data included in an underlying tone to be overwritten;
- and
- means for transmitting the spectrum of tones that includes the one or more randomly selected and artificially boosted tones.
A computer program product, comprising:
- a non-transitory computer-readable medium, comprising:
- code for randomly selecting one or more tones on which to convey additional data;
- code for encoding primary data across a spectrum of tones;
- code for encoding the additional data on the one or more randomly selected tones and artificially boosting the one or more randomly selected tones to exceed a threshold;
- code for overwriting tones associated with the primary data with the one or more randomly selected and artificially boosted tones associated with the additional data;
- and
- code for transmitting the spectrum of tones that includes the one or more randomly selected and artificially boosted tones.
A wireless communications apparatus, comprising:
- a processor configured to:
- randomly select one or more tones on which to convey additional data;
- disperse primary data across a spectrum of tones;
- include the additional data on the one or more randomly selected tones and artificially boost the one or more randomly selected tones to exceed a threshold;
- overwrite tones encoding primary data with the one or more randomly selected tones exceeding the threshold;
- and
- broadcast the spectrum of tones that includes the one or more randomly selected and artificially boosted tones.
