摘要：In thi s pa per we prop ose a co mpa ct MIMO system in frequency-selective fad ing channels which imp roves the performance of Wi reless Media. A MIMO bea m formi ng system mod el with mutua l co upling and matchi ng netwo rk is proposed t o cope with freq uency-select ive fading channels. The overal l syst em p ropo sed transfer matrix is deri ved using Z-para meter method . The system using the transform matrix which accepts the rela y a nd the delay ma trix for the co mputatio n. Then appl y the diversit y criteria by which we ca n make the code outp ut pa ir which is d istinct. So we can ob tain two different pairs one is shows the belo w va lue i n the MIMO System o ne is the Hig her value. It is the only way to achieve orthog onall y. One p articular pro blem wit h thi s is that it has uneven power a mong the symbol s it transmits. This means tha t the signal do es not ha ve a constant envel ope and that the po wer each antenna must tra nsmi t has to vary, bo th o f whi ch a re undesirabl e. We can tak e the middle value which overcomes thi s pro blem.
