Abstract

The author examines the correlation parameters of interest in a direct-sequence code-division multiple-access (DS-CDMA) communication network using M-ary frequency shift keying (MFSK) modulation. It is shown that the key multi-user interference parameters can be written in terms of cross-correlation functions with respect to a sinusoidal weighting function. The presence of these weighting functions is found to increase the peak cross-correlation of commonly used spreading sequences by a significant amount. One example shows an increase in the peak cross-correlation of 40%
