Performance Analysis of Coded Modulation Concatenated CCK and Low-Density Parity-Check Code

In this thesis, the performance of complementary code keying is compared between optimal decoding and majority logic decoding algorithm, and analyzed in fading channels. A structure concatenating low-density parity-check code and complementary code keying and the algorithm of soft-decision output for complementary code keying are presented, the simulation result show more better performance than complementary code keying in rayleigh fading channels.
