Accurate Performance Analysis of DS/SS Systems in Single-tone Interference over Flat Fading Channels

The performance analysis of DS/SS system in single-tone interference is usually presented for AWGN channel. While, there usually exists fading over the actual wireless channels. Using the well-known MGF-based analysis approach, the exact symbol error rate of DS/SS system in single-tone interference over flat fading channel is derived in this paper, and the application conditions of two familiar performance analysis methods — standard Gaussian approximation and improved Gaussian approximation for DS/SS system in single-tone interference are discussed.
