Average error probability for DS-SSMA communications - The Gram-Charlier expansion approach
Abstract
The average bit error probability for a binary asynchronous direct sequence spread spectrum multiple access system with or without white Gaussian noise is evaluated using the Gram-Charlier expansion approach. This method provides a good approximation to the average error probability for a larger number of users than previous techniques. However, if the number of users is few or the signal to Gaussian noise ratio is high, this method may not offer good results. Fortunately, previous methods can be used in this situation. Numerical results are presented for a set of linear m-sequences and a Gold code.
