Title:
通信装置、制御方法、分散アンテナシステム及びコンピュータプログラム
Document Type and Number:
Japanese Patent JP7278732
Kind Code:
B2
Abstract:
To provide a communication device, a control method, a decentralized antenna system, and a computer program capable of detecting changeover of a UL signal and a DL signal transmitted by a time division multiplex system with high accuracy.SOLUTION: A communication device has a receiving part, a self correlation acquisition part, a synchronizer, and a changeover section. The receiving part receives signals transmitted by a time division multiplex system. The self correlation acquisition part acquires a self correlation value of an input signal. The synchronizer detects a symbol head included in the input signal on the basis of the self correlation value. The changeover section changes over transmission operation of an uplink signal and transmission operation of a downlink, on the basis of detection results of the symbol head. Furthermore, the synchronizer confirms the symbol head on the basis of a reception state of a first symbol head candidate received earliest, out of multiple symbol head candidates having a self correlation value of a prescribed threshold level or more, a second symbol head candidate having the largest self correlation value.SELECTED DRAWING: Figure 3
