Abstract
A synchronous acquisition device for a small-circuit-scale CDMA receiver is provided. The synchronous acquisition device for a CDMA receiver, which receives as a receiver signal a spectrum-spread signal generated by spectrum-spreading, using a spreading code, transmission data including one of first to mth pieces (m: an integer 2 or more) of fixed data, comprises, for each of a plurality of paths into which the receiver signal is branched, a multiplier () for multiplying the receiver signal by the spreading code, an integrator () for one-symbol-time integrating an output signal from the multiplier (), fixed data sequential output units (to) having the first to mth pieces of fixed data and sequentially outputting the first to mth pieces of fixed data, and a second multiplier () for multiplying an output signal from the integrator () by the first to mth pieces of fixed data sequentially outputted from the fixed data sequential output units.
