摘　　要：文中在网络容量和覆盖的理论基础上,对TD-SCDMA,WCDMA和GSM的网络规划及影响因素进行了数学分析和仿真,研究了增大功率和扇区化方式对他们的影响。揭示了WCDMA的软容量的引入使它能服务更多用户,并得出WCDMA上行链路频谱效率为GSM的1.56倍,下行链路为GSM的1.88倍;在比较TD-SCDMA和WCDMA的链路预算差异后,得出TD-SCDMA覆盖小区半径更占有一定优势。The paper, based on theory of coverage and capacity, describes the math analysis and simulation on plans and influence of TD-SCDMA, WCDMA and GSM. Then, the influence of system capacity and coverage when using the increased power and the mode of sectoring is studied. For WCDMA, the introduction of soft capacity can make it serve more users. And by analyzing their differences of link-budgets, the coverage radius of TD-SCDMA is better than that of WCDMA.
