Abstract
Method for decoding a signal sent over a bandwidth-expanding communication system, where both channel estimation and signal detection are carried out on a set of samples generated by sampling the received signal at a sub-Nyquist rate, thus allowing for a significant reduction of the complexity of the sampling device of receivers using said method, as well as a significant reduction of their computational requirements.
Claims33
Method for decoding a signal (y(t)) sent over a bandwidth-expanding communication channel, comprising the step of sampling the received signal (y(t)) with a sampling frequency (fs) lower than the sampling frequency given by the Shannon theorem, but greater than the rate of innovation (ρ) of said received signal (y(t)), for generating a set of sampled values (y(nTs)).
