MMSE Block Linear Equalizer Algorithm for Joint Detection in TD-SCDMA Systems

MATLAB implementation of the Minimum Mean Square Error Block Linear Equalizer (MMSE-BLE) algorithm for joint detection in TD-SCDMA systems. Joint detection algorithms play a critical role in TD-SCDMA systems by enhancing system performance and capacity. The MMSE-BLE represents a widely-used equalization technique that mitigates interference and distortion during signal transmission. This algorithm operates on the minimum mean square error criterion and processes received signals through block-based equalization to improve signal quality and reliability. Our MATLAB implementation includes key components such as channel matrix estimation using training sequences, covariance matrix calculation for interference suppression, and equalization weight computation through matrix inversion operations. The program evaluates algorithm performance using bit error rate (BER) analysis, signal-to-interference ratio measurements, and computational complexity assessments. Performance validation demonstrates the algorithm's effectiveness and applicability in TD-SCDMA system scenarios, with particular emphasis on multi-user detection accuracy and real-time processing capabilities.
