摘要：
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握手一响应协议，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，可以靠地满足恶劣无线环境下数据传输要求。

Abstract:
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 res idual BER is very high. Thus, this scheme can meet the requirements of data transoortation in tough wireless environments.
