然而由于移动台的尺寸和载频的限制，使多天线技术很难实现。
However, due to the size of a mobile and carrier frequency constraints, multiple antennas can not be possibly implemented.
由于移动台只需使用一个天线，因而设计简单，成本低廉。模拟结果显示使用本方案后TD CD MA系统的性能获得很大提高。
Because only one receiving antenna is needed, the mobile handset is easy to design with low cost. Simulation results show that performance is greatly improved.
适用于移动的台分集天线要求紧凑的天线结构，端口之间较大的隔离度以及较小的相关系数。
Diversity antenna which is adapted for mobile station needs compact antenna configuration, high isolation and small correlation coefficient between multiple ports.
