【摘要】：基于对数正态分布的无线和电力线信道衰落,考虑发射功率、中继位置和脉冲噪声等因素,该文对室内无线和电力线双媒质协作的放大前传和译码前传中继系统进行建模和性能分析。针对对数正态分布衰落下积分求解性能闭合表达式的难题,首先利用对数正态分布变量和近似与Q函数变换等分别推导了放大前传和译码前传中系统采用选择式合并时的理论性能;接着根据理论计算和仿真分析了功率分配、中继位置、信道衰落和脉冲噪声参数等影响系统性能的规律。仿真验证了推导的理论性能的可靠性和准确性,相关结论为双媒质协作通信技术的应用提供了必要的理论支持。
[Abstract]:The lognormal distribution and power line based on wireless channel fading, consider transmitting power, relay position and pulse noise and other factors, modeling and performance analysis of the indoor wireless power line and double media cooperation amplify and forward and decode and forward relaying system. According to the lognormal fading problem solving performance of closed form integral first of all, the lognormal distribution and variable approximation and Q function transformation are deduced and DF in the prequel amplification system adopt the selective theory of performance at the time of the merger; then according to the theoretical calculation and simulation analysis of the power allocation, relay location, channel fading and impulsive noise parameters influence the performance of the system is verified by simulation rule. The theory is the reliability and accuracy, provides the necessary theoretical support for the application of the relevant conclusions double media cooperative communication technology.
