abstract
This letter examines The correlation parameters of interest in a DS-CDMA communication network using M-ary FSK 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. Mean-squared interference is also studied and can be expressed in terms of the auto-correlation of the spreading sequences used. This is a generalization of a well-known result for binary DS-CDMA systems. 1994 IEEE.
