CHAPTER 1 INTRODUCTION wireless communication systems: time-division division multiple-Access (TDMA) and code division multiple-access (CDMA) For the TDMA system, the following spatial processing techniques: optimum and (DMI) were reviewed; and eigenanalysis-based combining direct matrix inverse processing, or the eigencanceler was proposed. An analysis of system performance shows that the eigencanceler is superior to DMI when small data sets are available. For the CDMA system, the following receiver consecrations are formulated and The objective compared: (1) space-time (SMRC/TMRC) (in effect space- maximum ratio combining of this time diversity), (2) cascade optimum space-MRC time (SOPT/TMRC) (optimum spatial dissertation is processing cascaded with a RAKE receiver) and (3) cascade optimum space-optimum to present time (SOPT/TOPT). applications of space-time Background Information processing Wireless communication offers universal network access by removing users' location and for the time constraints. As wireless networks proliferate and the subscriber community following increases, the load on the network increases. The tremendous growth in network bandwidth has driven the convergence of voice, video, and data to IP based networks.
