Improved Energy Efficiency of Massive MIMO-OFDM

Today the world is moving towards the 5G technology in order to achieve high data rates, high throughput and low latency. To overcome the situation, this research work simulates and analyzes the 5G symbol with other conventional signals. The OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple Input and Multiple Output) technology plays a vital role in Symbol detection. Using detectors various attributes of the signals such as signal/noise ratio, Bit Error Rate and various signal parameters are simulated and their performances are monitored using MATLAB. Here, this research work majorly focuses on the techniques of SLM (Selective Mapping) and PTS (Partial Transmit Sequence) for analyzing the signal parameters such as PAPR (Peak to Average Power Ratio) and SNR (Signal to Noise ratio). OFDM is used for long distance communication as it reduces the interference and noise. MIMO system has n number of transmitters at the input and receivers at the output side. The MIMO used here for symbol detection has better performance compared with other existing system. The operation of the 5G system can be extended in the areas of mobile broadband, IOT devices and in vehicles. By analyzing the signal parameters, the quality of the signal could be improved which is again an added advantage.
