摘要： A detected signal (111) contains a preamble portion which includes symbol alternations, followed by a unique word portion, and a data portion. The unique word is selected to minimize the probability of erroneously detecting symbol alternations due to symbol errors. Each time a symbol alternation is detected, a correction value calculation section (102) averages the phase shift in the detected signal (111) for a predetermined length, thereby calculating a correction value (115). The correction value determination section (103) stores a plurality of correction values (115) in a chronological order. When the unique word portion is detected, the correction value determination section (103) retains, as an effective correction value (118), a correction value which is arrived at by going back a predetermined number of correction values among the stored correction values. A phase rotation section (104) corrects the phase of the detected signal (111) by using an effective correction value (118) calculated by the correction value determination section (103).

摘要： 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)); asecond 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 , QB r ) from frequency components included in the sampled in-phase signal (I(nT)) and the sampled quadrature signal (Q(nT)); and first and second delay detection operating sections (103, 104) for performing a delay detecting process based on the partial band signals and outputting detection signals.

摘要： A signal adding device for adding n input signals, comprising n A/D converters, a selector, and a lowpass filter. The n input signals are sampled in sequence by the A/D converter and digitized. Each digitized data is time-division multiplexed by the selector and input to the lowpass filter. The lowpass filter eliminates unnecessary higher-frequency components that are generated by the sampling of the A/D converter. The signal output from the lowpass filter consists of the baseband components only, that is, the signal is equal to an added signal of n input signals.

摘要： A diversity receiver carries out error detection, error correction, and data detection on each detected data string (21). An output switching unit (17) outputs a decoded data string (24) of a branch selected by a branch selector (16). The branch selector (16) selects a branch of highest priority in priority information (29) from branches of which a data detection signal (25) indicates that the data is valid and of which the number of error symbols (22) coincides with a minimum value. In the priority information (29), higher priority is assigned to a branch that includes an antenna of which the coverage is closer to that of an antenna included in a branch selected at the immediately-previous time. Thus, selected from the plurality of branches having the minimum number of error symbols (22) is the one that includes the antenna of which the coverage is closest to the coverage of the antenna included in the branch selected at the immediately-previous time. Therefore, it is possible to suppress the occurrence of misselection of a poor-quality branch, and improve a reception characteristic.
