| Summary: | This report presents details study of CDMA technique for mobile
communication systems. The objective of this project is to understand the spread
spectrum techniques including DS-CDMA and also to explain IS-95A system. The test
results for simulation on the IS-95A Reverse traffic channel are included to evaluate the
performance of the channel under various traffic conditions. Various conditions are
applied to the system to decide on the best performance. The performance of the channel
was measured in terms of BER. Reasonable Doppler shift frequency is determined. It is
found that performance of the system vary with the reduced of data rate. Amount of
AWGN added to the signal represents the interference generated by other base station
nearer. Therefore changes of SNR in the AWGN Channel provoke the system
performance. The detection performance improves with an increase in the SNR. |
