摘　　要：通过合理假设与范例分析,表明将软件无线通信中通用的可扩展硬件平台应用于传统蜂窝通信网后,可以实现快速的越区切换,而且与传统的蜂窝系统相比,能够带来更低的中断率,提高系统的覆盖半径;最后证明了采用闭环发送分集方案,可以大大改善接收能干比,提高系统的前向容量。By way of the reasonable supposition and exemplification analysis, it stated clearly that it can realize the fast switch across areas after the general expandable hardware platform in software radio was applied to traditional communication cell network. And it would cause lower interruption rates and increase the coverage radius of the system compared with traditional honeycomb systems. Finally it is proved that the closed-loop transmission scheme can improve the receiving the energy and the interference ratio and increase the forward-link capacity of the system.
