基于BSC9132平台的双波形DSP软件系统设计

Design of Dual Waveform DSP Software System Based on BSC9132 Platform

随着4G移动通信系统的普及以及5G通信技术的快速发展,地面移动通信系统的高速数据接入能力为人们的日常生活带来了极大的便利,然而在某些特殊领域,如海上通信、海上与岸基通信、地空通信等,由于其地理条件的限制,通信仍然存在极大的不便。对此,文章介绍了一种基于Freescale BSC9132平台DSP的双波形并发通信基站软件系统设计。双波形并发指宽带波形与窄带波形并发,其中宽带波形用于提高数据传输能力,而窄带波形用于扩大覆盖范围,实现单基站对数十公里到数百公里范围的中远距离通信覆盖,作为舰载、升空基站应用于这些特殊领域。

With the popularity of 4G mobile communication systems and the rapid development of 5G communication technolo⁃gy,the high-speed data access capability of terrestrial mobile communication systems brings great convenience to people's daily lives.However,in some special areas,such as maritime communications,communications between maritime and shore-based,ground-to-air communications,etc,due to restrictions on its geographical conditions,communication still has great inconvenience.In this regard,the paper introduces a dual-waveform concurrent communication base station software system design based on Fre⁃escale BSC9132 DSP platform.Dual waveform concurrency means wideband waveform and narrowband waveform concurrency,the wideband waveform is used to improve data transmission capability,while the narrowband waveform is used to extend coverage to achieve long-distance communication from tens of kilometers to hundreds of kilometers for a single base station,and sed as a ship⁃borne base station and airborne base station in these special areas.
