Abstract

We describe and propose the usage of a new codeword set to achieve the symbol rate (or spreading factor) adaptation in a CDMA communication network. Then we analyze the performance of a symbol-by-symbol, non-coherent, maximum-likelihood, blind spreading factor detector. The probability of false detection, which is also referred as the detection error rate (DER) in other studies, is analyzed for a multi-rate CDMA communication link with AWGN. The analysis shows that when the SNR is greater than 17 dB, the probability of false detection is around 10^-6.
