| 摘 要： | 根据ARQ协议传输每比特数据的等效能耗数学模型，针对无线传感器网络结构特点，分析研究了在高斯白噪声和瑞利衰落噪声信道中MIMO和协作SIMO分集的传输能耗与误帧率的关系特性；通过数学论证和计算机仿真，指出MIMO分集传输较之单路非分集传输消耗更多的能量，而协作SIMO分集传输则使得能耗更低，且最低能耗均与误帧率有关。

| Abstract: | In this paper,transmission energy consumption of MIMO(Multiple-Input Multiple-Output) diversity and cooperative SIMO(Single-Input Multiple-Output) diversity is researched for ARQ protocols on the equivalent energy consumption model per bit in wireless sensor networks.By means of mathematics and computer simulation,the comparison is made between diversity transmission and no-diversity transmission for energy consumption.The results show that energy consumption of MIMO diversity transmission is high,but it of... |
