BER Calculation Script for BPSK Modulation with MIMO ZF-SIC Equalization

This script implements a comprehensive Bit Error Rate (BER) calculation for Binary Phase Shift Keying (BPSK) modulation in a wireless communication system. The simulation environment models a Rayleigh fading channel with 2-transmitter and 2-receiver Multiple-Input Multiple-Output (MIMO) configuration. The core algorithm employs Zero Forcing Equalization combined with Successive Interference Cancellation (ZF-SIC) to enhance signal detection performance. Key implementation components include: - BPSK modulation mapping (bits to symbols conversion) - Rayleigh channel matrix generation with complex Gaussian coefficients - ZF-SIC equalizer implementation featuring interference cancellation ordering - Signal detection with iterative interference subtraction - Error counting and BER calculation metrics The code structure follows communication system simulation best practices, including signal transmission, channel impairment modeling, equalization processing, and performance evaluation. The ZF-SIC algorithm is implemented with proper matrix operations for interference cancellation, ensuring accurate MIMO signal recovery in fading conditions.
