Abstract: A system causes a scan angle of a directional antenna to change temporarily from a current scan angle to at least one trial scan angle during reception of predetermined portions of an information carrying signal. At the trial scan angle(s), a trial metric associated with each trial scan angle is determined by the system. The system then selects a next scan angle based on the trial metrics. Examples of predetermined portions of the information carrying signal include the Power Control Bit (PCB) and certain symbol periods of the Forward Error Correction (FEC) block.

Abstract translation: 系统使得定向天线的扫描角度在接收信息携带信号的预定部分期间暂时从当前扫描角度改变为至少一个试射扫描角度。 在试验扫描角度，与每个试验扫描角度相关联的试验度量由系统确定。 然后，系统基于试验度量来选择下一个扫描角度。 信息携带信号的预定部分的示例包括功率控制位（PCB）和前向纠错（FEC）块的某些符号周期。
