Patent ID: 8059707

Claim:
A decoding unit for decoding a modulated signal, the decoding unit comprising: a summing unit having i) a first input, ii) a second input, and iii) an output, the summing unit configured to i) receive the modulated signal at the first input, ii) receive a feedback signal at the second input, and iii) output a first waveform based on the modulated signal and the feedback signal; a demodulation unit having a first demodulation pathway and a second demodulation pathway, the demodulation unit configured to i) select between the first demodulation pathway and the second demodulation pathway, ii) receive and demodulate the modulated signal with the first demodulation pathway, and iii) receive and demodulate the first waveform with the second demodulation pathway; and a remodulation unit in communication with the first demodulation pathway and the second demodulation pathway, the remodulation unit configured to selectively i) output a first complex waveform based on the modulated signal, and ii) output a subsymbol waveform of the first waveform.
