【摘要】 在ＰＣＮ中，应用时分多址方式（ＴＤＭＡ）和动态信道指配（ＤＣＡ）可提高频谱利用率，增大系统容量，由于同道干扰对系统性能影响很大，信道（包括载波与时隙）必须仔细地加以分配，本文应用离散随机事件的方法模拟了多路同时进行的链路，讨论了３种不同的信道分配方法并分析了系统性能。更多还原

【Abstract】 The combination of time-division-multple-access(TDMA)digital radio technology and dy-namic channel assignment(DCA)can achieve high capacity and spectral utilization in PCN,Cochannelinterference is the major impairment to attain this object.To achieve good transmission quality thechannel(combination of carrier and timeslot)must be assigned to user carefully.A diserete-eventstochastic simulation of many concurrent two-way calls is adopted to analyze several different channelassigment strategies in the paper.更多还原
