Performance Comparison of Various Interference Suppression Algorithms

Application Context: In LTE communications, MIMO-OFDM technology effectively addresses intra-cell user interference but introduces more severe inter-cell interference. Inter-cell interference significantly limits system capacity and degrades service quality for edge users, making interference mitigation a critical research focus. Technical Approach: This program simulates the performance of multiple MIMO-based interference suppression algorithms including Interference Rejection Combining (IRC), Maximum Ratio Combining (MRC), Zero-Forcing (ZF), and Minimum Mean Square Error (MMSE). The implementation generates Bit Error Rate (BER) curves for straightforward algorithmic performance comparison, with code structuring that allows modular evaluation of each technique's interference cancellation capabilities.
