To accomplish this, you need to create a custom codec ( short for coder-decoder ). 要实现此目的,需要创建一个定制codec(即编码-解码器的简写)。
This thesis reviews the theories of wavelet-based coder-decoder. Provide the structure wavelet-based coder-decoder based on FPGA. 本文首先回顾了基于小波分析理论的基带波形成形理论,提出了基于FPGA的实现结构。
Traditional cipher is big volume, low in efficiency, and also cost high, all these problems have brought forward the single-chip voice cipher, integrative technology and speech coder-decoder, cryptology and modem technology would be well combined in a single-chip voice cipher. 针对传统密码机体积大、造价高、效率低下问题,本课题提出了单芯片语音密码机,它是集成化及语音编码、调制解调和加密技术的完美结合。
