Patent

CA 2437065

An object of the present invention is to provide a data receiving device enabling reduction in time required for extracting the partial band signal, and capable of being easily made in a simple structure as an LSI device without requiring a plurality of analog circuits having the same characteristics A data receiving device 1 includes: a first sampler 100 for sampling an in-phase signal I(t) at every predetermined sampling period and outputting the sampled in-phase signal I(nT); a second sampler 101 for sampling a quadrature signal Q(t) at every said predetermined sampling period and outputting the sampled quadrature signal Q(nT); a partial band extracting section 102 structured by a complex filter for extracting partial band signals IB r, QR r from frequency components included in the sampled in-phase signal I(nt) and the sampled quadrature signal Q(nT); and first any. second delay detection operating sections 103, 104 for performing a delay detecting process based on the partial band signals and outputting detection signals.
