Abstract:-In this paper, challenge about the condition of channel state info (CSI) in multipleinput multipleoutput (MIMO) systems supported space time block codes (STBC) over slow time- varying Rayleigh attenuation channels are addressed. We develop a novel MIMO control
assessment algorithmic rule that adopts a pilot symbol assisted modulation (PSAM) which has
been proved to be effective for attenuation channels. In this approach, pilot symbols are
periodically inserted into the information stream that's sent through the orthogonal STBC encoder.
At the receiver, we propose a simple MIMO channel estimation methodology before getting used
by STBC decoder. Simulation results indicate that the proposed pilot-assisted MIMO conception
provides accurate channel estimates. The impact of Doppler frequency on performance scheme is
also investigated by simulation
