| Abstract: | CDMA systems are the main multiple access technology, which can carry out the multi rate transmission. In this paper, power control by different rate, channel configuration and SNR & BER under multiple access interference are analyzed by multi rate transmission scheme of CDMA on multi processing gain,and system probability of error under multi rate for the numbers of different rate users on SPW(Signal Processing Workshop is simulated. |
