混合网络数据动态交换时隙再分配方法仿真

现有的混合网络数据动态交换时隙再分配方法,存在时延较大、时隙利用率较低等问题,提出基于WCDMA和数据链的交换时隙再分配方法,去除信道中的干扰信号,补偿由于数据传输造成的信号衰弱,通过信道的信干比估计,完成对信道的处理。当前分配时隙资源不能满足信息发送所需时,会在固定时隙内,周期性的发送时隙再分配消息给混合网络单元,并提出所需时隙资源,根据时隙动态分配方法,定制出混合网络时隙分配表,通过定制的时隙分配表,实现对混合网络数据动态交换的时隙再分配。仿真结果表明,所提方法能够在低时延、高时隙利用率的情况下,实现对混合网络数据动态交换时隙的再分配。

Simulation of Dynamic Exchange Time Slot Redistribution Method for Hybrid Network Data

The existing time slot redistribution methods for dynamic data exchange in hybrid networks lead to large time delay and low utilization rate of timeslot.Therefore,a method of reallocating exchange timeslot based on WCD-MA and data link was proposed.Firstly,the interference signals in channel were removed to compensate for the signal weakness caused by data transmission.Then,the channel processing was completed by estimating the signal-to-in-terference ratio of channel.If the current allocation of timeslot resource could not satisfy the information transmission,the message timeslot redistribution was sent to the mixed network unit in the fixed timeslot periodically.Meanwhile,the required timeslot resource was put forward.According to the dynamic allocation method of timeslot,the table of mixed network timeslot allocation was made.By customizing the timeslot allocation table,the redistribution for time-slot of dynamic data exchange in mixed network was achieved.Simulation results show that the proposed method can reallocate dynamical exchange timeslot in mixed network with low time delay and high timeslot utilization.
