摘要

在抗震救灾、抗洪抢险等应急通信专网场景下，需要高可靠、低延时的通信服务性能，提升信道利用率是一种提高通信服务性能的有效手段.由于可以将多个连续或者非连续的信道聚合起来，大幅提高信道利用率，多信道绑定是面向未来突发应急响应通信网络中的一种潜在解决方案.本文结合信道绑定思想，针对应急通信专用网络场景中无中心设备的分布式网络结构特点和信息基础设施的易失性特点，突破信道组合的传统思路，提出一种基于多信道绑定的应急终端协同的新方法，通过多终端相互协同的信道评估、基于任务类型的多信道分配和多信道绑定，减小由于各个节点时空不同带来的信道状态不确定性，提升分布式网络中的传输质量和信道利用率.论文创新性地提出信道状态因子的概念，通过信道中数据量的大小来量化信道的状态，在此基础上进行信道评估.通过软件定义无线电硬件平台与MATLAB联合仿真验证所提出方法的正确性，并搭建两节点收发的实验系统，通过实际测试和实验数据分析证明系统实现的可行性和有效性.

Abstract

In many special network application scenarios of emergency communication

such as disaster rescue and relief after earthquakes

floods

and other emergencies

a low delay and high reliability communication network is required. Improving channel utilization is an effective way to improve the performance of communication services. Since multiple continuous or non-continuous channels can be aggregated to greatly improve channel utilization

multi-channel bonding is a potential solution for future-oriented emergency response in the communication network. Combining the idea of channel bonding

this paper breaks through the traditional idea of channel combination

and proposes a method of multi-channel bonding based on multi-terminal cooperation

which faces the characteristics of the distributed network structure with no centralized device and the volatility of information infrastructure deployed in the emergency communication scenes. Through multi-terminal collaborative channel evaluation

task type-based multi-channel allocation and multi-channel bonding method

the uncertainty of channel state caused by the difference temporal-spatial constraints of each node is reduced

and the transmission quality and channel utilization in distributed networks are improved. The paper innovatively proposes the concept of channel state factor to quantify the state of the channel by the amount of data in the channel

and performs channel evaluation on this basis. A software-defined radio hardware platform with MATLAB software evaluates the correctness of the proposed theory. In addition

a two-node transceiver experimental system proves its feasibility and effectiveness through actual testing and experimental data analysis.
