Patent ID: 7310398

Claim:
A symbol synchronization device, comprising: a primary demodulation section for receiving a spread modulation signal where chips for symbol synchronization are attached to a symbol data after spread modulation and demodulating the spread modulation signal to a base band spread modulation signal; symbol synchronization chip removal means for removing said chips for symbol synchronization from said base band spread modulation signal; a secondary demodulation section for despreading the base band spread modulation signal from which the chips for symbol synchronization are removed by said symbol synchronization chip removal means; a symbol timing regeneration section for regenerating a symbol timing by performing in-phase addition of the base band spread modulation signals demodulated by said primary demodulation section; and a symbol decision section for deciding the symbols for the despread signals that are output from said secondary demodulation section, synchronizing with the symbol timing regenerated by said symbol timing regeneration section.
