Abstract:

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.

1. Introduction

Multiple-input Multiple-output (MIMO) works with multiple antennas at the transmitting end as well as at the receiving end. This structure helps to create sub-channels which are parallel over the common time and frequency axis. As a result of this, within the same bandwidth, the high transmission rate can be achieved [1] . In contrast to this, OFDM is a promising technique in terms of high spectral efficiency, bandwidth efficiency, robustness against frequency selectivity and simple implementation. With the help of this, the available spectrum will get divided into a number of orthogonal and narrowband subchannels which are overlapping on each other. So it increases its demand in a next-generation wireless communication system as one of the promising modulation schemes for higher data rate transmission. MIMO combines with OFDM in order to offer high diversity as well as multiplexing gain with the help of multiple antennas [2] , [3] and achieves the potential of both techniques and produces frequency flat MIMO channels. So in the downlink of LTE commercially
