The challenge to enhance the capacity of a CDMA system therefore lies in interference management. Many techniques that control and/or suppress interference in CDMA systems by transmit and/or receiver side processing .In this project we will implement two techniques for multiuser detection these two techniques are for 2 users in CDMA system and will analyze on basis of SNR The two techniques are • Least mean square algorithm • Blind mud algorithm First of all we will generate m sequences for our system. After that we will generate data which is to be send. Then we will follow the step of encoding of data using both algorithms for user detection. After that we will analyze the results on basis of • Mean square error • Signal to noise ratio
