The steadily decreasing cost of wireless communications and its growing development have resulted in its increased popularity. But the drawback here is limited bandwidth of transmission medium and multipath interference. So an important challenge in wireless system design is the selection of an appropriate multiple-access scheme. Among many multiple access strategies developed so far, CDMA (Code Division Multiple Access) based on IS 95 plays an important role. CDMA system can handle multipath effects and thermal noise on a communication network. So probability of poor call quality and dropped calls are reduced. This book includes study of a CDMA system and design of a MATLAB model of it. Here performance of CDMA system is analyzed for different parameters compared with previous analog or digital mobile systems. Receiver design also given special attention by designing an work optimal RAKE receiver as compared to other receivers .Reduction of multipath effect can be achieved by this RAKE receiver design .Finally real time implementation of CDMA encoding and decoding using TMS320C50 DSP kit is explored in great detail in this book.
