Portable terminal bureau, the gain setting expedient which sets the fixed gain

摘要

Depending on the fixed gain setting value by setting a fixed gain setting value is a predetermined gain value in the initial synchronization time is set, (10) amplifies the signal received from the radio base station movement terminal station. Then, (10), when detecting the synchronization signal pattern from the received signal is amplified, detection of the signal pattern is successful synchronization, automatic gain control as the initial value of the automatic gain control the fixed gain setting mobile station controls to perform, if the detection of the signal pattern fails synchronized, to change the fixed gain setting value.
