Title:

SYNCHRONOUS ACQUISITION DEVICE FOR CDMA RECEIVER

Document Type and Number:

WIPO Patent Application WO/2001/022639

Kind Code:

A1

Abstract:

A synchronous acquisition device for a small-circuit-scale CDMA receiver. A synchronous acquisition device for a CDMA receiver, which receives as a receiving signal a spectrum-spread signal generated by spectrum-spreading, using a spreading code, transmission data including one of first to mth pieces (m; integer of at least 2) of fixed data, and which comprises, for each of a plurality of paths into which a receiving signal is branched, a multiplier (21) for multiplying a receiving signal by a spreading code, an integrator (12) for one-symbol-time integrating an output signal from the multiplier (21), fixed data sequential output units (25¿1?-25¿m?, 24) having the first to mth pieces of fixed data and sequentially outputting the first to mth pieces of fixed data, and a multiplier (23) for multiplying an output signal from the integrator (12) by the first to mth pieces of fixed data sequentially output from the fixed data sequential output units.
