Abstract: The disclosed radio frequency signal transmitting and receiving apparatuses compensate for phase and amplitude differences without detecting sync timing of a calibration signal.
The radio frequency signal receiving apparatus consists of two or more antennas, radio frequency signal receiving units (12 and 13) each being connected to an antenna, a calibration signal generating unit (15) that generates the calibration signal having a cycle different from the cycle of a spread code, a radio frequency signal transmitting unit (14) that converts the calibration signal into a radio frequency signal, directional couplers (10 and 11) that add a radio frequency signal received by the respective antennas and the calibration signal in the radio frequency, a delaying unit (16) that delays a baseband signal from the first radio frequency signal receiving unit (13), a correlation detecting unit (17) that detects correlation between the output of the delaying unit (16) and the baseband signal from the second radio frequency signal receiving unit (12), a weight generating unit (18), and a complex multiplier (20) that compensates for the phase and gain differences between the radio frequency signal receiving units (12 and 13) based on the output of the correlation detecting unit (17).

Abstract: In a frequency-division multiplexing transmission apparatus for transmitting data in a frequency spectrum specific to a mobile station, a chip-dividing unit divides each symbol of a transmission-symbol sequence into chips; a first phase rotation unit performs π/2 phase rotation for the odd-numbered chips of the divided chips; a chip-repetition and rearrangement unit compresses the time domains of each chip of the chip sequence after phase rotation, then repeats the chips a specified number of times and rearranges the chips of the obtained repetitive-chip sequences so that they have the same arrangement as the original chip sequence; a second phase rotation unit performs phase rotation that changes at a speed specific to a mobile station for each chip of the rearranged repeti tive-chip sequence; and a transmission unit transmits said phase-rotated chips.

Abstract: In a calibration apparatus, which calibrates the phases of main signals input to each of the antenna elements of an array antenna (50), a calibration signal generation portion (62) generates calibration signals (C0 to C5), which are combined with main signals. An RF switch (63) alternately inputs to a wireless receiving portion (64) the signals radiated from other antenna elements via a first antenna element, and the signals radiated from other antenna elements via a second antenna element, and causes demodulation. The calibration detection portion (65) detects calibration signals from the demodulated signals, and the weight generation portion (66) uses the detected calibration signals to calculate calibration weights (W0 to W5), which are set in the phase shifter (53), to control the phases of main signals for input to each antenna element (A0 to A5).
