Abstract: A simple coding system that supports high speed communications is the differential orthogonal space-time block code (DOSTBC). The bit error probabilities (BEP) of DOSTBC utilizing M-ary phase shift keying mapping are derived. The BEP are first obtained for the static, independent and non-identical channels. The channel models considered include the Rayleigh, Nakagami-q, Nakagami-m, Rician, lognormal shadowed, composite Nakagami-m lognormal, composite Rice-lognormal, the Chun Loo's Land Mobile Satellite and a novel generalized Rice-lognormal channel.We then relaxed the static assumption and assumed the block-wise constant channel model. In this case, the BEP of DOSTBC are derived for the independent and identically distributed (iid) channels- which are assumed to be Rician/Rayleigh distributed. The BEP of DOSTBC are also derived for the iid Rayleigh channels when suboptimal diversity techniques, namely antenna selection combining schemes, are used.Some implications and applications of the BEP results to actual system designs are discussed.
