摘要： A HSDPA type mobile communication system includes a base station and a mobile station. The base station sets the uplink control channel with the mobile station to transmit a pilot signal. The mobile station measures a reception quality of the pilot signal to transmit the quality information to the base station using the uplink quality control channel. The base station performs transmission control of data for the mobile station using the quality information. The mobile station is set to perform control of starting and stopping transmission of the quality information so that the quality information is transmitted only as required. Therefore, power consumption in the mobile station can be reduced, interference wave power in the uplink can be reduced, and capacity of the uplink can be increased.

摘要： The invention provides a variable rate CDMA spread circuit which can obtain a sufficient number of spread codes (i.e., channels) orthogonal to each other in a mobile communication system which employs the CDMA scheme and has a plurality of channels of different bit rates. The variable rate CDMA spread circuit includes channel transmission processing units. An adder adds transmission signals output from the plurality of channel transmission processing units. A spread code generator generates a spread code (long code) having a long period and assigned in units of base stations. A spreader spreads the synthesized transmission signal with the spread code (long code). A modulator modulates the transmission signal spread by the spread means to convert it into a radio signal and outputs the radio signal to an antenna.

摘要： A mobile communication system is arranged to have a code divisional multi access system as in the North America standard system and to control a transmission power for reducing an influence of interference of one channel to the other ones by lowering a control error of the electric power transmitted on an up line. In the base station, a receiving section 106 of a tranceiving unit 100 provides a pilot symbol in-phase adding circuit 113 for detecting a carrier signal point represented by an in-phase component and an quadrature component at regular intervals. The amplitude of the detected carrier signal point is corrected by an amplitude correcting circuit 114 by using the previous control values for transmission power 116 read from a memory 115. Then, a predicting circuit 117 predicts a carrier signal point at a time when the next control for transmission power is executed by using the corrected carrier signal point. The predicted carrier signal point is compared with a reference signal through a comparing circuit 119. Next, a transmission power control circuit 121 generates a control value for transmission power at a time when the next control for transmission power is executed, transmits the control value to the mobile devices, and store the control value in the memory 115. The mobile devices control the transmission power based on the control value.

摘要： A coding and decoding system which uses CRC check bits is disclosed. When a coding apparatus performs coding, symbol interleaving is performed after coding by an outer code of a concatenated code, and coding by an inner code is performed after CRC check bits are added. Then, upon decoding by a decoding apparatus, error detection using the CRC check bits is performed after decoding of the inner code. After symbol deinterleaving is performed, decoding of the outer code by erasure decoding or error correction is performed depending upon the number of symbols included in a frame in which an error has been detected.

摘要： A data demodulator wholly consisting of digital circuits for time division multi-access (TDMA) signals subjected to differential phase-shift-keying (DPSK) is provided. The data demodulator generates a phase difference signal by subjecting .pi./4-shift quadrature phase-shift-keying (.pi./4 QPSK) signals to delayed detection of phase in synchronism with N-phase clock signals (where N is a positive integer), and reproduces a resulting phase difference signal into decision data. A first such data demodulator detects decision errors from the phase difference signal and decision data, and achieves symbol synchronism by sampling the decision data in a clock signal phase involving little decision error. A second such data demodulator supplies the phase difference signal after correcting its D.C. offset due to a frequency drift. In these two data demodulators, the formulas for computing said decision errors and correction values are flexibly varied according to preceding burst information.
