基于双帐篷映射的伪混沌编码器及其解码方法

Realization scheme of pseudo-chaotic encoder and decoder based on double-tent mapping

探讨了伪混沌跳时(PCTH)技术在超宽带(UWB)通信中的应用,提出了一种新的基于双帐篷(double-tent)映射的伪混沌编码器结构,并给出相应的解码方法。理论分析和Matlab仿真表明,与单帐篷(tent)映射相比该方案在不降低通信误码率的前提下有更强的抗破译能力,具有更高的安全性。

Based on the technology of pseudo-chaotic time hopping （PCTH） applying to ultra-wide bandwidth （UWB） communications, a new structure for the pseudo-chaotic encoder using double-tent mapping was presented, and a decoding scheme was given accordingly. The theoretical analysis and Matlab simulation result show that compared with tent-mapping, this scheme has a stronger anti-deciphering capabilities and better security without lowering the quality of communication.
