Abstract
A wireless communication device is described. The wireless communication device includes a receiver. The receiver is configured to determine a time-domain sample of a single carrier based on a received signal. The receiver is also configured to determine an estimated value based on the time-domain sample. The receiver is further configured to perform slicing based on the estimated value to produce a sliced value. The receiver is additionally configured to adapt a frequency-domain coefficient based on the estimated value and the sliced value. The receiver is also configured to perform channel equalization based on the frequency-domain coefficient.
Claims26
A wireless communication device, comprising:
- a receiver, wherein the receiver is configured to:
- determine a time-domain sample of a single carrier based on a received signal;
- determine an estimated value based on the time-domain sample;
- perform slicing based on the estimated value and in response to a determination of a channel condition to produce a sliced value;
- adapt a frequency-domain coefficient based on the estimated value and the sliced value;
- and
- perform channel equalization based on the frequency-domain coefficient.
A method performed by a wireless communication device, comprising:
- determining a time-domain sample of a single carrier based on a received signal;
- determining an estimated value based on the time-domain sample;
- performing slicing based on the estimated value and in response to a determination of a channel condition to produce a sliced value;
- adapting a frequency-domain coefficient based on the estimated value and the sliced value;
- and
- performing channel equalization based on the frequency-domain coefficient.
A non-transitory tangible computer-readable medium storing computer-executable code, comprising:
- code for causing a processor to determine a time-domain sample of a single carrier based on a received signal;
- code for causing the processor to determine an estimated value based on the time-domain sample;
- code for causing the processor to perform slicing based on the estimated value and in response to a determination of a channel condition to produce a sliced value;
- code for causing the processor to adapt a frequency-domain coefficient based on the estimated value and the sliced value;
- and
- code for causing the processor to perform channel equalization based on the frequency-domain coefficient.
An apparatus, comprising:
- means for determining a time-domain sample of a single carrier based on a received signal;
- means for determining an estimated value based on the time-domain sample;
- means for performing slicing based on the estimated value and in response to a determination of a channel condition to produce a sliced value;
- means for adapting a frequency-domain coefficient based on the estimated value and the sliced value;
- and
- means for performing channel equalization based on the frequency-domain coefficient.
