摘要：
研究了基于空时分组码的无线传感网协同传输系统节能传输的方法，提出了无线传感网单传输系统和基于空时分组码的协同传输系统性能的比较准则.针对无线传感器网络能源受限的特点，计算协同传输系统最优发射功率的门限电平.仿真结果表明，该门限电平在满足系统一定中断概率的条件下可以使无线传感器网络总传输功率达到最小.

Abstract:
STBCencoded cooperative transmission system in wireless sensor networks and its energy efficiency are investigated. A criterion for performance comparison between STBCencoded cooperative transmission and single transmission is proposed. The threshold of transmit power in cooperative transmission is calculated for energylimited wireless sensor networks. Simulation results demonstrate that the proposed threshold of transmitted power can minimize the overall networktransmission power with a certain outage probability.
Key words: cooperative transmission, outage probability, STBC, wireless sensor networks
