In this thesis, two full-rate space-time coded ofdm systems are proposed of the super orthogonal space-time trellis code (sosttc) in frequency selective fading . Space-time trellis codes have shown to provide a good performance in rayleigh fading channels recently super-orthogonal space-time trellis codes have shown to outperform these codes, and also provide a systematic design method to maximize diversity and coding gain in quasi-static rayleigh fading . Super-orthogonal space-time trellis codes (sosttcs) given in the literature are full rate and provide full spatial diversity with high coding gain in narro. Abstract: a new class of space-time codes called super-orthogonal trellis codes was introduced that combine set-partitioning with a super set of orthogonal space-time block codes in such a way as to provide full diversity with increased rate and improved coding gain over previous space-time trellis .
