A Design of Voice Communication System of Electromagnetic Filter in Strong Interference Environment

The article puts forward a voice communication channel equalization method based on a crosstalk decision feedback equalization and uses the transverse filter to electromagnetic interference, and then adopts the designs of hardware and software on the basis of this. System simulation results show that this voice communication system has good capability of anti-electromagnetic interference, better filtering performance, and effective improvement of signal-to-noise output ratio. In compare, this voice communication system functions better in communication distance, communication speed, and signal stability.
