Abstract
The intent of the work "Design of Code Division Multiple Access systems (CDMA) " is to consider different aspects of design with their effect on system performance. The generation of binary shift register sequences, that is maximal length sequences, with their properties are presented. From these maximal length sequences the Gold codes are obtained which are the most suitable approximately orthogonal codes for designing CDMA systems. These are discussed with their specific crosscorrelation properties. An extensive discussion is given of the difficult problem of synchronization, thatis bothacquisitionandtracking of pseudonoise sequences. Different synchronizing methods are discussed along with their relative performance. Moreover, an analysis of acquisition time is also provided for some acquisition systems. The spectral analysis for both unbalanced and balanced Gold codes are discussed. Overall CDMA system problems such as, the number of simultaneous users with a given level of interference and the number of users per unit bandwidth are analyzed. Also a comparision of CDMA, FDMA, and TDMA based on a bandwidth criterion is presented.
