Evolution of Diversity Gain with and without Coding Gain in MIMO for Emerging Wireless Networks
Abstract—The wireless networks are growing rapidly that cause constraint in data rate and power consumption. The multiple-input multiple-output (MIMO) has incredible performance to overcome the limitations by spatial multiplexing gain. Spatial multiplexing gain is achieved with the help of space time encoding technique in which a high rate signal splitting into multiple lower rate streams and transmitting them through the different antennas. This paper provides a comprehensive comparative study of diversity gain with and without coding gain for 4 × 2 and 4 × 4 MIMO systems. The coding gain is explored through turbo coding (TC) with ½ and ¾ coding rates, and diversity gain is adopted by orthogonal space time coding (OSTBC). Turbo coding is useful to reduce the forward error correction in multiplexed data transmissions. The compounding of OSTBC and turbo coding is valuables to increase data rate and reduce energy consumption by reducing bit error rate in emerging wireless network transmissions. Simulation results convinced the validity of proposed scheme.
