Title: Spread spectrum receiving device
Inventor: SUGAWARA YOJI
IPC: H04B1/707
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To reduce a synchronization acquisition time by varying the number of stages of matched filters corresponding to a reception state in the spread spectrum receiver used for mobile communication so as to enhance the general- purpose performance of the receiver. SOLUTION: A synchronization detection circuit 24 of the spread spectrum receiver receives a correlation output from a matched filter 1 and a synchronization/asynchronization state signal fed from a delay locked loop DLL 5. When the synchronization detection circuit 24 detects an asynchronous state, the circuit 24 gives a correlation output to a threshold level generating circuit 22 and a 1-tip delay circuit 24, then the 1-tip delay circuit 23 gives the correlation output of one preceding tip to the threshold level generating circuit to receive a current correlation output. The threshold level generating circuit 22 compares the received correlation output with the correlation output of one preceding tip to decide the number of stages of SR for the matched filter.  In the case of taking synchronization, a high correlation output is obtained earlier depending on the small/high stage numbers to have provision for the change in a spread rate thereby enhancing the general-purpose performance.
