一种移动信道数据传输的差错控制方案

An Error Controlling Scheme for Data Transmission in Mobile Channel.

在分析移动信道统计特性的基础上，提出了一种适合移动数据传输的自适应差错控制方案。该方案根据移动信道性能的变化自适应地选择纠错码。讨论了采用３种纠错码的原因，分析了它们的纠错能力及硬件实现的基本方法。计算机模拟结果表明，这种方案能实现可靠而有效的中速（４８００ｂｉｔ／ｓ）移动数据传输。

This paper puts forward an adaptive scheme for mobile data transmission on the basis of analysing the statistics characteristics of themobueChannel.This scheme selects threekinds of error correcting codes with the alteration of the channel adaptively.It states the reason why these three kinds of error correcting codes are used and their error correcting capacities and basic methods of hardware implementation are also discussed.Computer simulation reveals that this adaptive error controlling scheme can complete reliable and effective middle rate(4800 bit/s)mobile data transmission.
