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. WebbThe processing gain is given by 10 log [rc/rb], where rc is the chip rate, and rb is the data rate. For a chip rate of 1MBPS, and a data rate of 1KBPS, the processing gain is 10log[1000] or 30dB. The processing gain is a measure of immunity to noise, and jamming signals. Higher the processing gain, more the band spread of the signals. Higher ...

Analytical …

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.
