摘　　要：无线通信系统中速率自适应技术可适应无线信道条件变化,提高有效传输速率,是提升信道容量和无线传输灵活性的重要手段。针对传统通信系统速率自适应技术协议开销大、时延大、资源消耗大、速率切换不平滑的问题,提出了分段相位匹配接收的方式实现连续相位系统盲速率自适应接收,发送端可单方改变发送速率,同时在接收端实现速率盲检测。理论和仿真结果表明,连续相位调制系统盲速率接收技术具有时延低、资源消耗小且速率切换平滑的优势,特别适用于战术通信/数据链系统,工程实用性较强。The rate-adaptive technology in wireless communication systems can adapt to changing wireless channel conditions and increase the effective transmission rate,which is an important approach to improve channel capacity utilization and wireless transmission flexibility.In order to overcome the problems of protocol overhead,large time delay,high resource consumption,and unsmooth rate switching in traditional communication system rate-adaptive technology,this paper adopts a method of segmented phase matching reception to realize blind rate-adaptive reception of continuous phase system,in which the transmitter can change the sending rate unilaterally,and the receiver can realize the blind detection of the rate at the same time.Theoretical and simulation results show that this method has the advantages of low delay,low resource consumption and smooth rate switching.It is especially suitable for tactical communication and data link systems and has good engineering practicability.
