Abstract :
The paper before you is an evaluation of the IS-95A CDMA forward link and reverse link performance. We have devised some numerical results based on the real time simulation of the forward link and the reverse link under constraints imposed by the regular A WGN and REYLEIGH faded channels along with the mobile users imposed limitation. This simulation can also be used to deduce results for practical CDMA system designing. We have come up with graphical relationship between the BER (bit error rate) and SNR (signal to noise ratio).
