Title: Low Complexity Multi User Detection Using Decision Feed Back Equalizer 

Author Name: Ravindrababu, P. Venumadhav , Krishnarao 

Synopsis: 

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.
