Realization of Low Cost Simplex 23GHz Digital Microwave Link for Audio Modulation Transmission

摘要

In this paper we describe realization of low cost 2Mbit/s digital simplex link at 23GHz for Digital Audio Modulation Transmission in urban areas. Usage of jitter attenuator after demodulation and extremely low residual BER of 1E-10 gives excellent audio performances. The main requirement was low cost which is achieved by usage of direct modulation and avoiding costly digital signal processing wherever is possible. Measured results are given.
