The use of digital wireless communication systems has become more
and more common during recent years. A multiple-input-multiple-output
(MIMO) system techniques can be implemented to enhance the capacity of
a wireless link. We have investigated the performances of MIMO detectors
: Linear detectors(ZF detector, MMSE detector), SIC(Successive Interfer-
ence Cancellation) signal detectors, Maximum Likelihood detector, Sphere
decoding. In SIC signal detection we use MMSE weight matrix
