当接收到短脉冲检测开始触发信号时，向自动增益控制放大器(201)输出一个增益控制信号，以便用最大值进行放大。

Upon reception of a burst detection start trigger signal, a gain control signal is output to an automatic gain control amplifier (201) so as to perform amplification with a maximum value.

而且，可以发送增益值，它可用来控制在8-PSK操作期间的收发信机中的可变增益放大器（VGA）。

Furthermore, a gain value may be sent which may be used to control a variable gain amplifier (VGA) within the transceiver during 8-PSK operation.
