Abstract
Space-time code designs commonly rely on the assumption of independent and identically distributed (i.i.d.) Rayleigh channels. However poor scattering conditions can have detrimental effects on the performance of space-time codes. In this paper, we derive new Space-Time Trellis Codes that are robust in the presence of a large variety of propagation conditions. First, robust space-time trellis codes are derived when the transmitter has no channel knowledge. Then, trellis codes exploiting some statistical knowledge of the channel at the transmitter are presented. Codes satisfying those criteria are shown to perform much better in real-world channels than codes designed only for i.i.d. channels.
