Patent Images
1. A method of processing data, the method comprising:
- maintaining, at a first apparatus, a first clock signal;
transmitting, from the first apparatus, a clock synchronization signal for synchronizing a second clock signal, at a second apparatus, to the first clock signal;
receiving, at the first apparatus, one or more packets comprising a first set of samples indicative of an input over a period of time, the first set of samples corresponding to the second clock signal; and
generating, at the first apparatus, a second set of samples based, at least in part, on the first set of samples, wherein the second set of samples corresponds to the first clock signal.

Abstract
Certain aspects of the present disclosure relate to a method for compressed sensing (CS). The CS is a signal processing concept wherein significantly fewer sensor measurements than that suggested by Shannon/Nyquist sampling theorem can be used to recover signals with arbitrarily fine resolution. In this disclosure, the CS framework is applied for sensor signal processing in order to support low power robust sensors and reliable communication in Body Area Networks (BANs) for healthcare and fitness applications.
