Abstract

Multiple input multiple output (MIMO) system with millimeter wave frequency is one of the most important technologies in fifth generation of wireless communication systems. This paper presents the performance evaluation for the MIMO system based on Space time block code (STBC) in millimeter Wave frequency range. MIMO-STBC is an efficient technique to solve problems in 5G due to increasing the density of transmitted information and obtain higher data rates with limited bandwidth and power This technique is applied under different modulation schemes (Binary Phase Shift keying (BPSK), Quadrature Phase Shift keying (QPSK), Quadrature Amplitude Modulation(M-QAM) and Trellis Modulation Code (TCM) to improve the capacity, reliability and moreover minimize BER with limited bandwidth and transmit power. Moreover, the method is verified using Adaptive white Gaussian Noise (AWGN), Rayleigh and Rician fading channel to prove its effectiveness, with different number of antennas at transmitter and receiver sides) 2×2), (3×3), (4×4) MIMO-STBC. The presented method has been applied using MIMO system in MATLAB simulation program. The results of simulation show that (4×4) STBC MIMO system has been better performance than (2×2) and (3×3) STBC MIMO system. also, BPSK can be minimize the BER than QPSK, M-QAM, TCM. and the Rician fading distribution give slowest BER than Rayleigh fading distribution.
