Krishnarao Journal on Electronics Engineering 2249 – 0760 1 3 10 13 Linear Equalizers, Decision Feedback Equalizers (DFE), DS_CDMA This paper implements the transmission and reception of different number of user signals modulated by Binary Phase Shift Keying (BPSK) using CDMA. The transmitting signal goes through the communication channel. It is a medium that is between the transmitter and receiver and is modeled by the impulse response of multi path fading channel and it consists of additive White Gaussian Noise that is AWGN channel. The Decision Feed Back Equalizer (DFE) used to identify different user signals and then demodulates them to get all different user signals. Simulations shows the Decision feedback equalizers (DFE), compared with the Linear equalizers is simulated using MATLAB. March - May 2011 Copyright © 2011 i-manager publications.
