Abstract

The US government has designed new military standard vocoder algorithm, which is called MELP algorithm, to provide robust communication performance on poor channel environment. In this paper, we analyze transmission effect of security communication in MELP vocoder environment of HF channel. MELP vocoder develop properly application in environment of HF channel and influence of MELP vocoder and channel encoding apply to in envitonment of wireless burst and performance of plaintext communication and security communication study a matter from analysis of MOS and spectrum analysis.
