This paper introduces its functions based on which gives the design of half-duplex wireless data transmission module. 主要介绍该芯片的功能特点,并以该芯片为基础设计一种低成本的半双工无线数据传输模块。
In this article we analyse the shortcomings of the basic control protocol ( BCP) in the use of asynchronous half-duplex computer transmission according to real condition of the Single-side-band channel, and raise some improving schemes. 本文根据短波单边带信道的实际情况,分析了基本型链路控制规程(BCP)在异步半双工数据传输中的不适应性,并提出了相应的改进措施。
However, due to the half-duplex constraint of relay node, the relay transmission needs to consume double the resources compared to the traditional direct transmission, which will bring capacity loss to wireless relaying communication systems. 但是,由于中继的半双工特性,相对于传统直接传输,中继传输则需要消耗双倍资源,这将会带来无线中继通信系统的容量损失问题。
