Bit error rate in mobile communication is of parameters which effect on performance of network then effect on service quality of network. There are many technique used to improve this performance one of these techniques are equalization. As we know there are many type of equalization here in our article we will use zero forcing equalizer (ZF) and zero forcing with successive interference cancellation(ZF-SIC) which technique used to improving zero forcing equalization in another meaning used this technique to combat Inter-symbol interference (ISI) in network as our goal to improve quality of service (Qos).
