Title: Optimum demodulation circuit for cdma communication system, optimum demodulation method and paging system
Inventor: SHIMIZU TOSHIMITSU
IPC: H04W84/02
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To allow a base station to obtain an optimum reception timing from received data in the CDMA communication system. SOLUTION: Four-value FSK modulation is applied to RF data 102 as primary modulation and spread modulation by GMSK modulation is applied as secondary modulation. An initial value control section 25 outputs an inversely spread code in a set timing. A multiplier 10 applies inverse spread by using an inversely spread code. A maximum value sum section 23 sums four signals that are FSK-demodulated with maximum power for a prescribed symbol block. An optimum reception control section 24 changes setting of the initial value control section 25 every time one sum is obtained to obtain values as to all timings where an optimum reception timing is possibly in existence within a maximum delay time. Then the timing taking a maximum sum is discriminated to be the optimum reception timing.
