Performance Analysis Of New Modified Prime Sequence Codes For OCDMA System

In this paper a non coherent, optical synchronous CDMA system is considered. Here we present an analysis of the bit error rate for new modified prime sequence codes for λ=2. Further the various parameters related to the weight and prime sequence number have been analyzed to increase the size of the code family. Behaviour shows that by increasing the weight and prime sequence number more number of simultaneous users can be accommodated. But it's better to increase the prime sequence numbers P than the weight w because for higher values of simultaneous users there is less difference in the bit error rate by decreasing the value of P.
