SYNCHRONIZATION DETECTION APPARATUS AND WIRELESS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a synchronization detection apparatus and a wireless device which establish the synchronization when a plurality of users are assigned to the same channel.

SOLUTION: Each of a plurality of digital transmission signals to be sent and received has a training symbol row which is different each corresponding user. The synchronization detection apparatus 32 is provided with a plurality of correlating detectors 32.1 to 32.M which correspond to the plural users each. Each of a plurality of correlating detectors is provided with a transversal filter which receives input signals uj including a plurality of digital transmission signals. Multipliers 304.1 to 304.N+1 receive signals from each of a plurality of taps in one side input and receive users' training symbol rows äw(i)} to correspond to other side input each. An adder 310 adds the signals from the multipliers 304.1 to 304. N+1 and generates a detection signal.
