Research on Vehicle Broadcasting Signal Reception Enhancement Technology Based on Multichannel SDR and DOA Algorithms
Modern in car broadcasting plays a crucial role in vehicle communication,connecting driver and external information,and playing a very important role in communication experience and vehicle safety.However,signal interference in urban environments and coverage issues in remote areas limit signal reception quality,weaken communication effectiveness and emergency response capabilities.The aim of this study is to optimize the signal reception performance of in car broadcasting,thereby improving communication quality.By combining multi-channel SDR modules with DOA technology,a corresponding hardware platform was built,and the directional enhancement characteristics of multi-channel antennas in vehicle applications and experi-mental environments were simulated,achieving experimental results in improving signal-to-noise ratio.This provides a useful technical reference for enhancing the reception of in vehicle broadcasting signals.
