数字跳频通信设备关键技术的研究与实现

Research and Realization of Digital Frequency-Hopping Communication Equipment

使用OMAP5912实现G723.1语音编解码,经过信道编解码,以及ARM与DSP的相互通信,实现了数字跳频手持设备.描述了该实现过程,以及所涉及的跳频通信理论、信道编码理论和语音编码技术、与设备所使用的TIOMAP嵌入式系统平台、射频模块、语音编解码芯片的软硬件环境.

This paper introduces the realization of encoding and decoding of G723. 1 by using OMAP5912, some processes and principles of realizing digital frequency-hopping communication equipment through the encoding and decoding of channels, as well as the interactive communication of ARM and DSP. This paper also introduces the theories of frequency-hopping, of channel encoding, and the techniques of speech encoding, as well as the software and hardware environment of the TI OMAP embedded system platform, frequency-emitting module, and CMOS chip of speech encoding and decoding.
