摘要： Transmission channel estimation is performed for NT×NR reception signals and estimated transmission channel values are thereby output. The estimated transmission channel values are divided into N groups of NT×M estimated transmission channel values and a covariance matrix with M rows and N columns is obtained for each of the estimated transmission channel value groups. The N covariance matrixes are averaged over a predetermined range in terms of at least a time or a frequency (first averaging). Eigenvectors are generated based on respective N averaging outputs. Transmission channels between base station antennas and terminal antennas are generated from the eigenvectors and the estimated transmission channel values. Covariance matrixes are obtained for the generated transmission channels. The covariance matrixes are averaged over a different range from the range used in the first averaging (second averaging) and a beam forming weight is obtained by combining the generated eigenvectors.

摘要： A multicarrier receiver that receives N carrier frequencies therein comprises N A/D converters each of which analog-digital converts a receive signal at a sample rate fs for each carrier, N quadrature detectors which receive outputs sent from the N A/D converters therein and digitally quadrature-detect the outputs, respectively, 2N LPFs which allow only desire bands of outputs of the N quadrature detectors to pass therethrough, and N delay time correcting means each of which corrects a processing delay time deviation for each carrier inside the multicarrier receiver in a time unit of less than 1/fs using a fractional delay filter. The delay time correcting means has, for example, an M-stage shift register which operates at fs and generates a delay of M/fs, and a fractional delay filter which operates at fs and includes an even number of tap coefficients and which generates a delay different from M/fs by 0.5/fs.

摘要： A distortion compensator that compensates for distortion arising in a main amplifier 10 that amplifies a signal effectively compensates for third order distortion which is unbalanced between the higher frequency band and lower frequency band. An amplitude detector 3 detects the level of a signal subject to amplification and a signal level change direction detection means 7 detects the direction of change in the level of the signal. A signal level change control means 4-8 stores the correspondence between the signal level and the mode of changing the signal in order to compensate for distortion for when the direction of change in the signal level is positive and when it is negative, and controls a signal change means 9 so that the amplitude and phase of the signal is changed in a mode of changing the signal corresponding to the detected direction of change in the signal level and the detected signal level. A signal change control content updating means 11-13 updates the content of this correspondence so that the distortion contained in the signal after amplification is reduced.

摘要： A wireless communication device and method are capable of detecting a receive timing of a direct wave at higher precision without increasing transmit power. A signal receiver receives a signal having a center frequency changed in a predetermined rule at predetermined time intervals. A time-frequency transformer transforms the received signal from a time domain to a frequency domain. A filter removes frequency-domain signal components unused during reception, based on the predetermined rule, from the frequency-domain signal. A reverse modulator performs a reverse modulation process on the remaining signal components. A signal adder generates an added signal by performing accumulative addition on the signal components that underwent the reverse modulation process in the reverse modulator for a predetermined period. A direct wave arrival time determiner determines an arrival time of a direct wave according to an impulse response obtainable from an output of the frequency-time transformer.
