摘要： A code acquisition device securing reliable code acquisition and reducing a time required for a code acquisition procedure. In the device, a sampler samples an input signal, and a searcher continuously searches for a spreading code used for the sampled signal until the phase of the spreading code is acquired. A verifier verifies whether the phase of the spreading code used for the sampled signal is acquired, according to the search result of the searcher. The searcher initializes and restart the verifier whenever the phase of the spreading code is searched.

摘要： A decimation filtering apparatus using interpolated second order polynomials compensates for a droop caused by a CIC (Cascaded Integrator-Comb) filter. The decimation filter includes a CIC decimation filter for decimation filtering the sampling signal to downconvert a sampling signal; an ISOP filter for monotonically increasing an output of the CIC decimation filter to compensate for a passband droop caused by the CIC decimation filter; a multistage halfband filter including at least one modified halfband filter for half-decimating a signal output from the ISOP filter, thereby downconverting the ISOP filter output signal; and a programmable FIR filter that compensates for a passband droop of a signal output from the multistage halfband filter.
