    摘要: A MIMO wireless communication system capable of relaxing a reduction in a transmission rate on a cell end far from a base station and ensuring a high transmission rate for a mobile station, irrespectively of a distance from the base station is provided.In a state 1, the mobile station 21 checks a propagation line quality and instructs only the first base station 11 to transmit data to the mobile station 21. In a state 2, the mobile station 21 issues a request to divide the data to the first base station 11 and the second base station 12 and to transmit the divided data to the mobile station 21, and holds MIMO communication with the two base stations.In a state 3, the mobile station 21 requests only the second base station 12 to transmit the data and communicates with the second base station 12.

    摘要: There is provided a mobile radio communication system which is capable of reducing a group ID in length with respect to the number of mobile stations and realizing efficiency of air resources. Suspend control of mobile stations is performed by notifying not only control information but also transmission/reception state update information for instructing a state [Active/Suspend] in a status update frame set in advance from a base station to the mobile stations using an HS-SCCH. The base station performs the suspend control by sending, in state update information at timing of a state update frame number of a user ID allocated in advance, a group ID of a user ID allocated to mobile stations desired to be made Active in advance.

    摘要: A mobile phone set includes a base unit and at least one handset belonging to the base unit. In the base unit, a receiving section 11 receives a first modulated wave S.sub.1 which is a digital modulated wave from TX 3, and a demodulating section 12 demodulates the received wave, and further a decoding section 13 decodes the demodulated wave. Further, a detecting section 17 detects the demodulated wave. Further, a detecting section 17 detects that the decoded signal is of a calling signal for the handsets 2-1 and 2-2 associated with the base unit, and after the detection a controlling section 25 instructs a D/A converting section 14 to D/a convert a digital signal decoded by the decoding section 13 to an analog signal and a modulating section 15 to modulate the analog signal. A transmitting section 16 transmits a second modulated wave S.sub.2 as the analog modulated wave to the handset 2-1 or 2-2. Further, in the base unit 1, a receiving section 18 receives a third modulated wave S.sub.3 as the analog modulated wave from the handset 2-1 for example, and a demodulating section 19 demodulates the received wave.

    摘要: A mobile communication system capable of improving the reception characteristic using a small circuit size and low power consumption is provided. The channel vector estimating section 181 estimates channel vectors in a method such as a method in which the section 181 multiplies, according to the multipath timings sent from the multipath timing detecting section, the input signal from the base-station receiving section by a complex conjugate of a known pilot signal to average the input signal (to average the input signal by de-spreading the pilot signal in the case of CDMA). The noise estimating section 182 estimates noise power using received signals and generates a Channel matrix by arranging the estimated channel vectors according to the multipath timings. The weight calculating section 184 calculates a weight matrix using the noise estimation value and the Channel matrix and sets the obtained filter weight vectors to the equalizing filter 185.

    摘要: A radio receiver includes a channel estimation unit, phase difference vector generation unit, correction coefficient setting unit, and noise estimation unit. The channel estimation unit obtains a channel estimated value from a received signal at a predetermined period by using a known pilot signal. The phase difference vector generation unit obtains a phase difference vector between the preceding channel estimated value and the current channel estimated value. The correction coefficient setting unit sets a correction coefficient corresponding to the phase difference vector. The noise estimation unit obtains a corrected noise estimated value by correcting a noise estimated value on the basis of the received signal and the correction coefficient. A noise estimated value correction method is also disclosed.
