An Open-Loop Method of Controlling Narrow Band Channel Delay
In the narrow band data communication system, there are such problems as long time delay and random loss of data resulted by large amount of data from data source. The delay of a typical data transmission system consisted by DTE and DCE is resulted by several factors. Through the analysis of these factors, this paper presents a low-cost and open-loop software method to control the speed of the signal source. By increasing the interface speed and reasonably estimating the data package delay, this method can make the delay and the loss of data package controllable and prevent the random loss of data. This method can be applied to those low-speed communication transmission situations which have special requirement of the delay, such as short wave, ultra short wave, dial-up network, a line for special use and so on.
