摘要
为了优化空时分组编码(STBC)和混沌编码,提升无线通信的性能与可靠性,采用多基频混沌编码(MFCC)结合空时分组编码技术搭建了一种双重编码模型,并对该模型的编码解码性能进行仿真分析,评估模型的编码解码性能。实验结果显示,当信噪比为10 dB时,新模型的误码率低至10-8,并且能在两基频条件下实现3548 b/s的高吞吐量。表明该编码解码模型不仅能降低误码率,还能有效提高基频的吞吐量,为促进无线通信技术的发展提供了有力支持。
In order to optimize space-time block coding(STBC)and chaotic coding and improve the performance and reliability of wireless communication,a dual coding model was constructed by using multi-frequency chaotic coding(MFCC)combined with space-time block coding technology.The encoding and decoding performance of the model was simulated and analyzed to evaluate its encoding and decoding performance.The experimental results show that when the signal-to-noise ratio is 10 dB,the error rate of the new model is as low as 10-8,and a high throughput of 3548 b/s can be achieved under the condition of two fundamental frequencies.This indicates that the encoding and decoding model can not only reduce the bit error rate,but also effectively improve the throughput of the fundamental frequency,which provides a strong support for the development of wireless communication technology.
