碩士 === 國立中央大學 === 通訊工程學系 === 101 === A block fading channel is a common wireless communication channel model. Unlike pilot symbol assisted modulation (PSAM), noncoherent detection does not has the problem of rate loss due to pilot symbols. As far as we know, there are no research results of noncoherent block codes for block fading channels. In this thesis, we focus on this subject. First, short noncoherent block codes without structures are searched by computers. Then, a scheme of long noncoherent block codes composed of short noncoherent block codes is proposed. Finally, the obtained codes are concatenated with a turbo code for further improving the error performance. Simulation results show that, compared with PSAM, our codes have better error performance.
