摘要:
为了改善信道环境下复杂的水声通信系统性能,更好地实现资源的合理分配,采用跨层设计的思想,提出了一种基于ARQ反馈中继协作水声通信下行链路的资源分配方案.该方案利用目标端的反馈信息ACK/NAK(正确译码/错误译码),在给定目标的误包率、无法获取信源端信道的状态信息、相对复杂的水下环境以及中继会放大转发前路噪声的情况下,可以实现目标用户的调度和速率的分配.仿真结果显示,与传统的方案相比,利用所提出的方案,可以在相对复杂度较小的基础上实现较低的误比特率,达到接近信道状态已知时的性能.
Abstract:
To improve the quality of underwater acoustic communication system in the complex channel environment, a resource allocation schedule for relay-aided underwater acoustic communication system with ARQ(automatic repeatre quest)“feedback”was proposed.The schedule was used for amplifying the forwarding signal and using feedback information of ACK/NAK(correct decoding/wrong decoding)through the relay considering the target packet error rate and relatively complicated underwater environment. The user selection and the rate allocation were implemented. Simulation results show that compared with traditional schedules, the proposed schedule can obtain lower bit error rate under the condition of lower complexity, thus approaching the performance index of the known channel information.
