Abstract:
A method and system for demodulating high-order Quadrature Amplitude Modulation (QAM) signals is disclosed. In one embodiment, the system includes a cyclic prefix (CP) removal unit for removing a CP from a received signal to provide a first intermediate signal, wherein the first intermediate signal comprises a plurality of bits; a fast Fourier transform (FFT) unit configured to convert the first intermediate signal into a frequency domain; a soft de-mapper configured to derive a plurality of soft bits based on log-likelihood estimates of the plurality of bits, wherein the soft de-mapper derives each soft bit by using a single linear function to approximate each soft bit; and a decoder configured to decode a signal derived from the soft de-mapper into information.

Claim (Index 2):
The system of  claim 1  further comprising a parallel-to-serial (P/S) converter coupled between the FFT unit and the soft de-mapper, wherein the P/S converter is configured to convert the output of the FFT unit from a plurality of parallel bits to a serial bit stream.
