摘要： The present invention provides methods for combining antenna diversity and gain control in a communications system using a single chain of receiver electronics. A number of input parameters related to various characteristics of a received signal are used to determine the quality of the received signal. The antenna diversity and gain control procedures are enabled or disabled based on the signal quality. The antenna diversity procedure estimates the signal level of the non-operational antenna using an infinite impulse response digital filter. The gain control procedure selects one of three gain paths based on the received signal strength.
摘要翻译： 本发明提供了使用单链接收机电子装置在通信系统中组合天线分集和增益控制的方法。 使用与接收信号的各种特性相关的多个输入参数来确定接收信号的质量。 基于信号质量启用或禁用天线分集和增益控制程序。 天线分集过程使用无限脉冲响应数字滤波器来估计非操作天线的信号电平。 增益控制程序根据接收到的信号强度选择三个增益路径中的一个。
