一种新型无线网络混合错误控制方案研究

Research on a New Hybrid Error Control Scheme for Wireless Networks

本文通过整合基于FEC的字节交织发送和自动请求重传技术,以及引入UDP握手-响应协议,提出一种新型的无线网络混合错误控制方案,并通过数学方法对其进行了性能分析。实验表明,通过选取合适的参数,本文所提方案在高误码率环境下网络数据传输成功率可达96%以上,可以可靠地满足恶劣无线环境下数据传输要求。

By integrating the bytes interleaving technology based on FEC and ARQ, and introducing a simple shaking- and-response UDP protocol, this paper presents a new hybrid error control scheme for wireless networks and evaluates its performance by conducting a mathematical analysis carefully. Experiments show that the success ratio of data transportation will get as much as 96% and even higher by adopting parameters elaborately in wireless networks when residual BER is very high. Thus, this scheme can meet the requirements of data transoortation in tough wireless environments.
