Abstract : We analyze wirelcss comtr~uriication systcrns employing nlult iple- transmit niultiplcreceive antennas in this thesis. Spacc-time codes haw bwn proposed in the literatureas an efficient means of coding over rnultiple transmit antennas. In particular. therank and the dcterniinarit of codc difference matrices have been shown to be importantin thc design of space time codes in quasi-static fading channels. In this thesis. weinvestigate the problem of rtia~imizing the coding gain givcn by the mininlum of thedeterminants of the code ciifference matrims. We show that equal singular valuesof the code differerice matrices is a necessary and sufficient condition for obtainingoptimal coding gain. We also show that equal singular values Lead to robust codes.Finally. we present the construction of enhanced dimensional trellis coded modulation(EDTCM) codes based on equal singular values.....-...,..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..
