SENSOR-BASED WIRELESS COMMUNICATION SYSTEMS USING COMPRESSIVE SAMPLING
First Claim
1. A method for sampling signals, the method comprising:
- receiving, over a wireless channel, a user equipment transmission based on an S-sparse combination of a set of vectors;
down converting and discretizing the received transmission to create a discretized signal;
correlating the discretized signal with a set of sense waveforms to create a set of samples, wherein a total number of samples in the set is equal to a total number of sense waveforms in the set, wherein the set of sense waveforms does not match the set of vectors, and wherein the total number of sense waveforms in the set of sense waveforms is fewer than a total number of vectors in the set of vectors; and
transmitting at least one sample of the set of samples to a remote central processor.
