Processing gain in spread spectrum
WebbProblem 1: Assume a direct sequence spread spectrum system where user 0 data =1,user 1data= −1,user2data= −1. Furthermore, the chip rate is 4 Mchip/s and each user uses the bit rate 250 kbps. a) Select suitable codes, determine the processing gain, estimate the communication band-width and sketch the CDMA baseband multiuser signal. WebbLarger spreading factors mean larger processing gain, and so a signal modulated with a larger spreading factor can be received with less errors compared to a signal with a lower spreading factor, and therefore travel a longer distance. For example, a signal modulated with the SF12 can travel a longer distance than a signal modulated with the SF7.
