Short-wave Radio Ale Technology And Its Modules To Achieve

As an key technology of shortwave automatic radio, Automatic Link Establishment (ALE) system features with functions such as channel real time evaluation technique, link establishment, signal and graph transfer and so on. According to the GJB 2077-94 and the requirement of automatic radio of HaiGe communication Co., a new way of bit synchronization is put forward. This article discusses the design of 8-FSK modulating and demodulating, signal detection, and FEC encoding, based on the technique of bit synchronization. ALE module is optimized and mended in its application, because it is a module of automatic radio of the company. As a result, automatic radio with this module has a high link probability in Gaussion Noise Channel, and all performances of the module meet the requirement of the design. At last, according the MIL-STD-188-141B, the next generation technique of the ALE module was discussed, and an original project was proposed. These work what I did pave the way for the development of the next generation radio of the company.
