<p>An subsystem processor for converting an input audio signal to complex audio samples for QADM processing by a modem for communication with a remote modem is disclosed. The audio process comprises a decorrelator for processing the input audio to generate a residual signal, an adaptive scaler for adaptively scaling the residual signal to generate a scaled residual signal, a randomizer for phase-randomizing the scaled residual signal to generate a complex signal with randomized phases, and a limiter for limiting the complex signal with randomized phases, such that the complex signal is transmitted by the modem to a remote modem.</p> |
