Abstract

In this paper, a performance comparison of orthogonal variable spreading factor (OVSF) codes and complete complementary (CC) channelization codes in Rayleigh fading channels is presented in the uplink. The bit error rate (BER) is simulated to provide a means of comparison for different spreading factors (SF) and different numbers of users. The system is totally asynchronous, and a special simulation strategy is applied to make the simulation of long scrambling codes possible. An introduction to the correlation functions utilized in the computation of the multiple access interference (MAI) seen by each user is given. Except the application of CC-codes, the simulation strictly sticks to the UTRA FDD standard.
