Implementing BPSK Equalization Technology Using Simulink

This implementation demonstrates Binary Phase Shift Keying (BPSK) signal equalization technology using Simulink. The system employs Maximum Likelihood Sequence Estimation (MLSE) equalization, which involves sophisticated signal processing algorithms despite its seemingly simple structure. The implementation covers complete communication chain components including BPSK modulation/demodulation modules, multipath channel modeling with configurable delay profiles, and MLSE equalizer with Viterbi algorithm implementation for sequence detection. Through the MLSE equalizer's trellis-based decoding approach, the system effectively compensates for inter-symbol interference caused by multipath propagation during signal transmission. The Simulink model incorporates configurable parameters for signal-to-noise ratio, channel coefficients, and equalizer memory depth, enabling comprehensive performance analysis of bit error rate improvement and system reliability enhancement under various channel conditions.
