Optimal Design of Waveform for Moderate Capacity Troposcatter Communication Systems
摘要
Abstract
To satisfy the application requirement of moderate capacity troposcatter communication,theoretical analysis of the anti⁃distortion ability and implicit diversity gain is made between distortion adaptive receiver and adaptive equalization.Troposcatter commu⁃nication system model using FEC is established.The BER and coding gain under different diversity scheme are analyzed.Based on this, an optimal design of pulse⁃shaping,signal processing method and FEC scheme is proposed. The BER performance of this scheme was measured through hardware platform realization.The result shows that the proposed scheme is easy to implement with a significantly im⁃proved BER performance.关键词
