• In this paper we determine the performance of a direct sequence spread spectrum multiple access system where the users utilize different carrier frequencies. This scheme is applicable to a system, such as an indoor wireless communication system utilizing very high frequencies, where the available bandwidth is so large that it is not feasible to spread the signal over the whole band. The multi-user interference is modeled as a compound Gaussian random variable and expressions are found for the variance of the interference as a function of relative phase and frequency parameters. In addition to different carrier frequencies the analysis also accounts for offsets in the chip clock frequencies, general chip pulse shaping function, and different received signal powers. We give results for the error probability in a multiple access system utilizing BPSK, QPSK, and OQPSK modulation.
