摘要： The present invention relates to orthogonal cover code generating apparatus, demodulation reference signal generating apparatus, and methods thereof. The demodulation reference signal generator comprises a non-correlation sequence generator configured to generate a non-correlation sequence for pilot of a first resource block; a first spectrum spreading unit configured to spread spectrums of elements in the non-correlation sequence for pilot to be mapped to a first frequency resource of the first resource block, by using a first group of Orthogonal Cover Codes (OCCs); a second spectrum spreading unit configured to spread spectrums of elements in the non-correlation sequence for pilot to be mapped to a second frequency resource of the first resource block, by using a second group of OCCs; the first and second frequency resources are adjacent frequency resources with respect to a first group of data streams, and the first and second groups of OCCs are mirrors in column to each other; and a mapping unit configured to map the spectrum-spread elements to the first and second frequency resources, respectively. The methods and apparatuses according to the present invention can enhance pilot randomization, remove the problem of pilot transmission power imbalance, and satisfy the requirement on orthogonality at the two dimensions of both time and frequency.

摘要： A direct-sequence spread spectrum signal receiving device may comprise a receiver unit, a chip sequence generating unit, a correlation unit, and comparison unit. The receiver unit may extract a chip stream from a radio-frequency signal, said chip stream containing a first chip sequence. The chip sequence generating unit may generate a plurality of trial chip sequences on the basis of a first trial chip sequence and on the basis of a plurality of index rotations. The correlation unit may determine a plurality of correlation values on the basis of said plurality of trial chip sequences and on the basis of said first chip sequence, each of said correlation values indicating a degree of correlation between a respective one of said trial chip sequences and said first chip sequence. The comparison unit may determine whether a maximum one of said correlation values exceeds a defined threshold value.

摘要： A direct-sequence spread spectrum (DSSS) signal receiving device (10) is described. The device (10) may comprise a receiver unit (22), a chip sequence generating unit (44), a correlation unit (28), and comparison unit (38). The receiver unit (22) may extract, in a detection phase, a chip stream from a radio-frequency signal, said chip stream containing a first chip sequence. The chip sequence generating unit (44) may generate, in said detection phase, a plurality of trial chip sequences on the basis of a first trial chip sequence and on the basis of a plurality of index rotations, each trial chip sequence being index-rotated relative to said first trial chip sequence by one of said index rotations. The correlation unit (28) may determine, in said detection phase, a plurality of correlation values on the basis of said plurality of trial chip sequences and on the basis of said first chip sequence, each of said correlation values indicating a degree of correlation between a respective one of said trial chip sequences and said first chip sequence. The comparison unit (38) may determine, in said detection phase, whether a maximum one of said correlation values exceeds a defined threshold value. A method is also described.
