摘　　要：在路由冲突下的激光传感节点通信中,低能耗调度传输信道受到多径效应的影响,导致调度的负载均衡性欠佳,信息传输的误码率较高。为了提高调度算法信道资源均衡调度能力,提出基于自适应反馈均衡控制技术的低能耗调度算法。首先,构建路由冲突下的激光传感节点通信低能耗调度算法传输信道模型,分析激光传感节点通信低能耗调度算法信道的多径特性;其次,采用线性随机化检测方法进行激光传感节点通信低能耗调度算法的信道码间干扰抑制;最后,结合自适应反馈均衡技术进行信道均衡设计,进行激光传感节点通信传输低能耗调度算法信道的多径抑制,实现激光传感节点通信低能耗调度算法信道资源均衡调度。测试结果表明,采用该算法进行激光传感节点通信传输低能耗调度的均衡性较好,抗干扰能力较强,输出误码率较低。In the laser sensor node communication under routing conflict,the low-energy scheduling transmission channel is affected by multipath effect,which results in poor load balance and high bit error rate of information trans-mission.In order to improve the channel resource balancing capability of scheduling algorithm,a low-energy schedu-ling algorithm based on adaptive feedback equalization control technology is proposed.Firstly,the transmission chan-nel model of low-energy scheduling algorithm for laser sensor node communication under routing conflict is constructed,and the multipath characteristics of low-energy scheduling algorithm channel for laser sensor node communication are analyzed.Secondly,the channel inter-code interference suppression of low-energy scheduling algorithm for laser sensor node communication is carried out by using linear randomization detection method.Finally,the channel equalization design is combined with the adaptive feedback equalization technology.The multi-path suppression of low-energy scheduling algorithm channel for laser sensor node communication transmission is carried out,and the channel resource equalization scheduling of low-energy scheduling algorithm for laser sensor node communication is realized.The test results show that the proposed algorithm has good balance,strong anti-jamming ability and low bit error rate.
