摘要： A transmitter, when the power changes at a certain timing, adjusts the gain for the transmission signal before the application of the distortion compensation process correspondingly to the amplitude of the transmission signal at the certain timing based on the average of the power of a transmission signal before application of the distortion compensation process, obtains a distortion compensation coefficient corresponding to the value of the power of the adjusted transmission signal from the LUT, applies the distortion compensation process to the transmission signal using the obtained distortion compensation coefficient, calculates an update for a distortion compensation coefficient corresponding to the obtained distortion compensation coefficient and stored in the LUT based on an error between the power of the transmission signal amplified by an amplifier and the power of the transmission signal before the application of the distortion compensation process, and updates the LUT using the calculated update.

摘要： In a calibration apparatus, which calibrates the phases of main signals input to each of the antenna elements of an array antenna, a calibration signal generation portion generates calibration signals, which are combined with main signals. An RF switch alternately inputs to a wireless receiving portion 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 detects calibration signals from the demodulated signals, and the weight generation portion uses the detected calibration signals to calculate calibration weights, which are set in the phase shifter, to control the phases of main signals for input to each antenna element.

摘要： Sample signals P0(0) to P0(N−1) are input for each symbol of a multiplexed transmission sample or transmission chip. The sum of a particular pair of sample signals (for example, a pair of P0(0) and P0(N/2)) is obtained by an adder for each pair of sample signals, and a signal the power of which is halved by attenuating the sum with an attenuator is generated and output as a dispersion signal P1(N/2). Additionally, a difference between the pair of the sample signals is obtained by a subtractor, and a signal the power of which is halved by attenuating the difference with an attenuator is generated and output as a dispersion signal P1(0). The dispersion signals P1(0) and P1(N/2) are made to respectively correspond to first and second subsymbols, which are configured by partitioning the symbol.

摘要： 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 each being connected to an antenna, a calibration signal generating unit that generates the calibration signal having a cycle different from the cycle of a spread code, a radio frequency signal transmitting unit that converts the calibration signal into a radio frequency signal, directional couplers that add a radio frequency signal received by the respective antennas and the calibration signal in the radio frequency, a delaying unit that delays a baseband signal from the first radio frequency signal receiving unit, a correlation detecting unit that detects correlation between the output of the delaying unit and the baseband signal from the second radio frequency signal receiving unit, a weight generating unit, and a complex multiplier that compensates for the phase and gain differences due to the radio frequency signal receiving units based on the output of the correlation detecting unit.

摘要： A signal separating unit separates an input signal into a first branch signal and a second branch signal in such a manner that, as the amplitude of the input signal decreases, the amplitude of the first branch signal and the second branch signal decreases and the difference between a phase of the first branch signal and a phase of the second branch signal increases and, as the amplitude of the input signal increases, the amplitude of the first branch signal and the second branch signal increases and the difference between the phase of the first branch signal and the phase of the second branch signal decreases. An amplifier amplifies the first branch signal. Another amplifier amplifies the second branch signal. A combining unit combines signals that are output from the amplifiers together, thereby generating an output signal.
