LDPC codes and expansion method

摘要

A MIMO transmitter comprises a scrambler; an encoder parser responsive to the scrambler; a forward error correction encoder responsive to the encoder parser, wherein the encoder applies a parity check matrix derived from a base matrix; an interleaver responsive to the forward error correction encoder; a QAM mapping module responsive to the interleaver; an inverse fast Fourier transform module responsive to the QAM mapping module; and an output module responsive to the inverse fast Fourier transform module.
