Bit Error Rate Analysis of 16 X 16 MIMO - OFDM in Downlink transmission for LTE - A

The fourth-generation (4G) cellular systems are assisted by radio access technologies comprising 3rd Generation Partnership Project (3GPP) Long-Term Evolution (LTE), and its improved version, LTE-Advanced (LTE-A). Generally speaking, Release-10 of 3GPP standards is referred to as LTE-A, furthermore, its achievable execution makes it a genuine 4G innovation as per the definitions are given by the International Telecommunication Union (ITU). LTE/LTE-A are rising communication technologies in transit toward 5G communication systems. The LTE-Advanced system uses multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM) techniques in order to achieve a high data rate transmissions. In LTE maximum data rate expected is 100 Mbps for downlink transmission and 50 Mbps for uplink transmission. MIMO-OFDM realizes the utmost spectral efficiency and hence, delivers the maximum data throughput and capacity. This research work is dealing with the investigation of execution dependent on release 10 of the 3GPP standard and investigates the performance analysis of Turbo coded MIMO-OFDM in LTE-A networks using 64-QAM modulation technique and 256 subcarriers. Bit Error Rate (BER) and downlink throughput are evaluated in terms of Signal to Noise Ratio (SNR) with 16 × 16 MIMO configurations in downlink using MATLAB simulation.
