An alternative derivation for the signal-to-noise ratio of a SSMA system
Sherry X. Wei · IEEE Transactions on Communications · 1994
We present an alternative derivation for the signalto- noise ratio (SNR) of a phase-coded spread-spectrum multiple access (SSMA) system by use of ensemble-average approach. We show that our formula can be explicitly expressed in terms of system parameters and the expression for the SNR in [l] is just a special case when the user number is very large.
