摘要：
The aim of this paper is to compare the bit error rate performance resulting from the application of OVSF, Gold and chaotic spreading sequences in WCDMA systems, when users can transmit at different bit rates. For this purpose, we adopt an analytical model that, starting from classic approaches, takes into account the modifications required to manage different spreading factors. We show that chaotic sequences have good potentialities, and could be considered for inclusion in the next generation of mobile radio.
