  • Patent number: 8223742
    Abstract: A multicarrier transmitting apparatus capable of providing a fast cell search. A base station apparatus (100), which serves as a multicarrier transmitting apparatus for transmitting frames each including, as synchronization channel sequences, first synchronization sequences (P-SCH sequence) used for timing determinations and second synchronization sequences (S-SCH sequence) different from the first synchronization sequences, comprises a frame forming part (130) that forms frames each including the first synchronization sequence (P-SCH sequence) disposed in each of subcarriers symmetrical with respect to a DC component subcarrier (DC subcarrier) in the frequency direction; and an RF transmitting part (160) that transmits the frames. In this way, a frame receiving end can use a filter having a polarly symmetrical pass-band and needs no frequency shifting process, with the result that the processing amount at the receiving end can be reduced and hence a fast cell search can be achieved.

  • Patent number: 8107900
    Abstract: A multi-carrier transmission device improves peak suppression efficiency in a multi-carrier signal. The multi-carrier transmission device (100) has a peak suppression unit (140) for dividing a multi-carrier signal into two parts: a first multi-carrier signal and a second multi-carrier signal. A peak signal detection unit (142) detects a power value at a predetermined interval concerning the first multi-carrier signal. When the detected power value is equal to or above a predetermined level, a peak extraction unit (144) extracts a signal component equal to or above the predetermined level from the first multi-carrier signal. A band limit filter unit (146) passes only a predetermined band from the extracted signal component. An adder (154) subtracts the signal component after the band limit from the second multi-carrier signal.
