Wireless communication with coded modulation and GSC over Rayleigh fading channels

We consider coded modulation with generalized selection combining (GSC) for wireless communication with reception diversity over Rayleigh fading channels. We derive analytical upper bounds on trellis coded modulation and bit-interleaved coded modulation. Except at low signal-to-noise ratio, simulation results show that our bounds are very tight. An asymptotic analysis on the pairwise error probability, which can be used as a guideline for designing coded modulation over GSC channels, is also given.
