摘要
研究混沌编码技术在超宽带无线通信中的应用。提出一种新的伪混沌编码器结构,根据新的编码器结构,给出两种相应的解码方法,比较它们在AWGN信道中的解码性能,仿真结果表明本文方法的有效性。
Chaos-modulation-based ultra wide band (UWB) communication was addressed. A new structure for the pseudo-chaotic encoder was presented, and some decoding schemes were also given accordingly. The performances of such decoding schemes were compared in the AWGN channel. Simulation results verify and demonstrate the effectiveness of the proposed method.
