Abstract
The downlink SINR performance for multi-rate W-CDMA systems is derived in this research when the concatenated OVSF/truncated PN code is used. The derivation is complicated by the fact that the auto-correlation term of the concatenated OVSF/truncated PN code is not a random noise. It is shown that this auto-correlation term can be approximated as a binomial random variable. The analytic SINR performance can be obtained based on this approximation, and it matches well with the numerical result.
