Analysis and Optimization of SIMO Systems with Adaptive Coded Modulation in Spatially Correlated Rayleigh Fading
— In this paper we investigate the performance of an adaptive coded modulation (ACM) system in single-input multiple-output Rayleigh fading channels with spatial correlation. The considered ACM system has a set of multi-dimensional trellis codes from which it can adaptively select the code best suited to the channel quality. The channel quality is tracked at the receiver by a predictor using a pilot-symbol-assisted modulation scheme. We optimize both the pilot spacing, and the power allocation to pilot and data symbols. The channel predictor is made optimal in the maximum a posteriori sense and the correlation to other subchannels is taken into account. A numerical example is given for flat Rayleigh fading subchannels with Jakes correlation profile.
