1. An apparatus comprising: a receiver module configured to process a signal received over a wireless channel, wherein the received signal reflects a source signal comprising a plurality of source symbols, and includes inter-symbol interference (ISI) effects induced based on a faster-than-Nyquist (FTN) signaling rate and a tight frequency roll-off applied to the source signal for transmission over the wireless channel, and wherein the receiver module comprises: an equalizer module configured to compensate for the ISI effects induced based on the FTN signaling rate and the tight frequency roll-off applied to the source signal; and a decoder module configured to decode an output of the equalizer module to determine and regenerate the source signal.
