Coded non-coherent orthogonal signals for the fading channel

We compare the performance of coded and pragmatic-coded modulation based on orthogonal signal sets with non-coherent detection over an independent flat Rician fading channel. Computation of the channel cut-off rate shows that, in this case, pragmatic-coded modulation is superior to coded modulation. By deriving bit error probabilities for actual coded and pragmatic-coded modulation schemes, we prove that the latter is competitive even for practical designs and for AWGN channels
