摘要

语音加扰/解扰一直是保密通信系统的关键组成部分。本文介绍了在德州仪器公司的TMS320C6711 DSP上实时实现频域语音置乱/解扰技术。三种技术，频率反演，跳频反演和滚动代码反演，已经成功实现。随后，对这些技术的结果进行评估，并根据其安全级别进行比较

Frequency-domain speech scrambling/descrambling techniques implementation and evaluation on DSP

Speech scrambling/descrambling has always been a key component in secure communication systems. The paper describes the real-time implementation of frequency-domain speech scrambling/descrambling techniques on Texas Instruments' TMS320C6711 DSP. Three techniques, frequency-inversion, frequency hopping inversion and rolling code inversion, have been successfully implemented. Subsequently, the results of these techniques are evaluated and compared on the basis of their level of security
