Abstract :
Space-time block code design and decoder design are addressed for code division multiple access (CDMA) systems. Optimal code designs are found by optimizing the Chernoff bound of the probability of decoding error. From this, the diversity gain and the coding gain are determined for the CDMA scenario. The resultant optimal code designs are classified and analyzed. Both optimal and moderate complexity suboptimal decoding algorithms are proposed and evaluated
