摘要：

This article presents a simple method for calculating the signal-to-interference-plus-noise ratio in direct sequence-code division multiple access systems with despreading sequences weighted by stepping chip waveforms. The method is based on a simple equality, which gives a relation among the number of occurrences of various chip patterns belonging to random spreading sequences. It is found that there is no need to scrutinize all the chips of a random spreading sequence to determine the number of transitions that occur between two consecutive chips. Several numerical examples and computation times are provided to demonstrate the validity and significance of this method.
