【摘要】：基于對數(shù)正態(tài)分布的無線和電力線信道衰落,考慮發(fā)射功率、中繼位置和脈沖噪聲等因素,該文對室內(nèi)無線和電力線雙媒質(zhì)協(xié)作的放大前傳和譯碼前傳中繼系統(tǒng)進(jìn)行建模和性能分析。針對對數(shù)正態(tài)分布衰落下積分求解性能閉合表達(dá)式的難題,首先利用對數(shù)正態(tài)分布變量和近似與Q函數(shù)變換等分別推導(dǎo)了放大前傳和譯碼前傳中系統(tǒng)采用選擇式合并時的理論性能;接著根據(jù)理論計算和仿真分析了功率分配、中繼位置、信道衰落和脈沖噪聲參數(shù)等影響系統(tǒng)性能的規(guī)律。仿真驗證了推導(dǎo)的理論性能的可靠性和準(zhǔn)確性,相關(guān)結(jié)論為雙媒質(zhì)協(xié)作通信技術(shù)的應(yīng)用提供了必要的理論支持。
[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.
