MIMO SC-FDMA System Performance Investigation Under Realistic Channel Models

Single carrier-frequency division multiple access (SC-FDMA) multiple input multiple output systems should be properly designed in terms of their complexity, and bit error rate performance. This can be realized by frequency domain equalization. In this paper, the research work is dedicated to analyze and investigate the performance improvement of these systems via frequency domain equalization schemes. The bit error rate, a function of the signal to noise ratio, is the performance metric of interest which is utilized to evaluate the system under different standard hypothetical and realistic channel conditions. Using quadrature phase shift keying. The simulation results indicate that the performance of the SC-FDMA system using the Joint Complex Regularized Zero Forcing schemes is highly competitive to the minimum mean squared error s and conventional zero forcing schemes assuming different Carrier Frequency Offsets, and channel models.
