Simulation of TLS Adaptive Beamforming Algorithm for Microphone Arrays

This implementation simulates TLS (Total Least Squares) adaptive beamforming algorithm for microphone arrays in English. The simulation allows adjustment of key parameters including microphone spacing and input signal bandwidth to achieve optimal beamforming output. The algorithm can be adapted to various acoustic environments and requirements by modifying parameters in the configuration file (e.g., config.m) where array geometry and signal properties are defined. Key implementation aspects include: - Array geometry initialization using microphone coordinates based on adjustable spacing parameters - Signal generation module with configurable bandwidth settings via frequency domain filtering - TLS algorithm implementation employing singular value decomposition (SVD) for robust weight calculation - Real-time beam pattern visualization through polar plot functions The algorithm's performance can be further optimized by implementing recursive updating methods for weight vectors and incorporating noise covariance matrix estimation techniques. This enhances the microphone array's signal capture and processing capabilities, particularly in noisy environments through improved sidelobe suppression and mainbeam steering accuracy.
