摘要： 为了降低移动设备的硬件复杂度,提出了一种基于发射天线选择和切换检测合并的传输机制。利用信噪比的概率密度函数,分别生成了相移键控调制、正交幅度调制、脉冲幅度调制的矩生成函数,将其进行积分,得到了平均符号误码率的精确表达式。将信噪比的概率密度函数进行积分,得到了中断概率的闭合表达式。仿真结果表明,系统的性能可以通过增加发射/接收天线数和衰弱系数、减小衰弱因子来改善。

关键词: 发射天线选择, 平均符号误码率, 中断概率, 切换检测合并, N-Nakagami信道

Abstract: In order to reduce hardware complexity of mobile devices, a new transmission scheme was proposed based on transmit antenna selection and switch-and-examine combining. The probability density function of the signal-to-noise ratio was used to generate the moment generating functions for phase shift keying modulation, quadrature amplitude modulation, and pulse amplitude modulation. By integrating the moment generating functions, the exact average symbol error probability expressions were derived. The exact closed-form outage probability expressions were also derived by integrating the probability density function of the signal-to-noise ratio. The simulation results showed that the system performance was improved with the transmitting/receiving antennas and the fading coefficient increased, while the fading factor decreased.

Key words: switch-and-examine combing, outage probability, transmit antenna selection, N-Nakagami fading channels, average symbol error probability
