MMSE Equalization Technique for MIMO-OFDM Systems Performance Analysis

Problem Definition

PROBLEM DESCRIPTION: In wireless communication systems, achieving reliable and secure transmission of data is a prime concern. One of the key challenges faced by designers is the interference caused by inter symbol interference (ISI) which can significantly impact the performance of the system, leading to a higher Bit Error Rate (BER) and reduced Quality of Service (QoS). In order to address this challenge, various equalization techniques have been developed, such as Maximum Ratio Combining (MRC) and zero-forcing equalization. This project focuses on analyzing the performance of the Minimum Mean Square Error (MMSE) equalization technique when applied in Multiple Input Multiple Output (MIMO) - Orthogonal Frequency Division Multiplexing (OFDM) systems. The MMSE algorithm is employed to mitigate the effect of ISI on the transmitted signal and improve the system's BER.

By evaluating the efficiency of the MMSE equalization technique through calculations of QoS parameters like BER and Peak-to-Average Power Ratio (PAPR), the project aims to assess the impact of this technique on the overall performance of the MIMO-OFDM system. Therefore, the problem statement revolves around determining the effectiveness of the MMSE equalization technique in reducing ISI and improving the BER of the MIMO-OFDM system. Through the implementation of this project using MATLAB software, the goal is to optimize the performance and reliability of wireless communication systems, ultimately enhancing the data transmission quality and security.
