Abstract	:	Using two transmit antennas and one receive antenna. Alamouti's schemes provide themaximum possible diversity gain with a maximum likelihood detector. In addition to diver-sity gain, this research maximizes the coding gain using the minimum of the determinantsof the code Merence matrices. In order to achieve the mtximum coding gain on a Rayleighfading channel, a trellis code is designed to maximize the free Euclidean distance. Rellis-coded modulation is combined with Alamouti's schemes to provide additional coding gain,The design criteria of trellii coded modulation is b d on Randon-Hurwitz matrices. Basedon these criteria, new space-time trellis coded QPSK schemes are designed and shown toachieve good performance relative to space-time block codes. The performance of this code-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
