摘要： A code division multiple access receiver estimates symbol values transmitted by different stations by despreading a combined received signal, weights the estimated symbol values by use of weighting factors calculated for the different stations, respreads the weighted symbol values to estimate the interference due to each station, and subtracts the estimated interference from the received signal to produce a residual signal. The weighting factors can be calculated from the residual signal; the weighting factors are calculated so as to minimize the power of the residual signal. The weighting factors are adjusted at certain intervals, preferably at intervals determined from the rate of fading of the received signal.

摘要： The present invention is provided with one main station and a plurality of substations. After transmitting data addressed to all substations, the main station transmits a message addressed to all substations to query whether reception was normal. When unable to receive data normally, the substations transmit a response message to the query message, but do not transmit a response message when data reception was normal. The time for confirming that transmission was normal or abnormal can be shortened by the main station transmitting data addressed to all substations only one time, and by the substations transmitting response messages only in the case of abnormal reception.

摘要： A drive motor control apparatus for a vehicle, wherein the vehicle has a motor and rotation detecting unit. In the apparatus, the first difference computing unit computes one of multiple first differences every time an actual detected angle of rotation of the motor becomes a corresponding representative angle during the one cycle. The first difference indicates an advancing amount of an estimated angle relative to the actual detected angle. The second difference computing unit computes multiple second differences based on the first differences of the one cycle. The second differences are adjusted in accordance with a degree of acceleration and deceleration of the motor. The adjusted second differences are used for correcting the actual detected angle of rotation of the motor.

摘要： A boost control section for controlling a converter includes a PI control section and a resonance suppression section. The PI control section calculates a basic command value based on a deviation between a drive voltage generated by the converter and a target voltage to equalize the drive voltage and the target voltage. The resonance suppression section calculates, based on the state of variation of the drive voltage, a correction value for correcting the basic command value to suppress the variation. The basic command value is corrected by adding the correction value. First and second drive pulses corresponding to the corrected command value are outputted to the converter.
