Abstract
A method of multi-mode communications includes receiving signals from multiple sources at a plurality of sample buffers, referencing the plurality of sample buffers for a first source at one time and referencing the plurality of sample buffers for a second source at another time, and communicating data from the referenced plurality of sample buffers to a processing unit. The processing unit concurrently receives inputs from buffers in the plurality of sample buffers and outputs to other buffers in the plurality of sample buffers.
Claims19
A method of multi-mode communications, the method comprising:
- receiving signals from multiple sources at a plurality of sample buffers;
- referencing the plurality of sample buffers for a first source at one time and referencing the plurality of sample buffers for a second source at another time;
- and
- communicating data from the referenced plurality of sample buffers to a processing unit, wherein the processing unit concurrently receives inputs from buffers in the plurality of sample buffers and outputs to other buffers in the plurality of sample buffers.
A method of multi-mode digital communications, the method comprising:
- asynchronously processing received communication samples at a processing unit, wherein the communication samples processed by the processing unit correspond to more than one communication protocol specification;
- controlling the processing unit by programmed instructions;
- and
- updating the programmed instructions based on processing factors.
A method of multi-mode digital communications, the method comprising:
- asynchronously processing received communication samples at a processing unit, wherein the communication samples processed by the processing unit correspond to more than one communication protocol specification;
- controlling the processing unit by programmed instructions;
- and
- selectively directing the communication samples from separate buffers to one processing unit of a plurality of processing units.
A system for multi-mode communications, the system comprising:
- means for receiving signals from multiple sources at a plurality of sample buffers;
- means for referencing the plurality of sample buffers for a first source at one time and referencing the plurality of sample buffers for a second source at another time;
- and
- means for communicating data from the referenced plurality of sample buffers to a processing unit, wherein the processing unit concurrently receives inputs from buffers in the plurality of sample buffers and outputs to other buffers in the plurality of sample buffers.
