ABSTRACT:
A system and method for receiving communication signals is provided. According to the method, a plurality of communication signals is received, each communication signal comprising one or more source signals. The plurality of communication signals are multiplexed into a multiplexed signal, which is then converted into a baseband signal. The baseband signal is sampled to produce a digital multiplexed signal comprising a plurality of samples. The samples are interpolated to generate respective interpolated digital signals, which are then subject to a blind signal separation operation to separate each of the source signals.
