摘要： In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols. Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.

摘要： In variable rate data transmission, a data transmission method or the like is provided which enables adjustment for achieving desired erroneous rate detection. A transmitting side places a calculated error detecting code after the transmission data in each frame, generates frame data in which an R-bit series before the final bit position of the error detecting code is rearranged in inverse order, and transmits. A receiving side assumes the transmission data and error detecting code by assuming the final bit position of the frame data in each frame, conducting the assumption presuming that the rearrangement in inverse order has occurred on the transmitting side. Among the assumed final bit positions, the position determined to be errorless as a result of the error detection based on the assumed transmission data and error detecting code is determined as the final bit position. R can be greater or less than the number of bits of the error detecting code.

摘要： A control for varying a maximum transmission power of a transmitter according to a propagation loss or a distance between the transmitter and a receiver is made possible to reduce deterioration of a user capacity to a minimum. In a wave propagation loss measurement section, a calculation is performed on the basis of an amplification factor of a reception amplifier, amplitude information and a base station transmission power information of a reception baseband signal to calculate a wave propagation loss of a reception signal, thereby estimating a propagation loss of transmission signal. The wave propagation loss information is inputted to a maximum amplification amount designation circuit to decide a maximum amplification factor. The maximum amplification amount designation circuit adjusts a maximum transmission power of the transmission signal by designating the decided maximum amplification factor to a transmission amplifier.

摘要： A cell search control that can save power consumption at a mobile device and perform an appropriate in-service area determination is provided. The mobile device according to the present invention includes: a cell search execution unit (120) for detecting a synchronization channel from a base station to perform cell search; a signal reception determination unit (130) for comparing a measurement X of the signal from the base station with a system information reception threshold A and determining whether or not to receive a system information from the base station; and an in-service area determination unit (170) for comparing the measurement X with a minimum required quality level B contained in the system information and determining whether or not to enter into an in-service area state with the base station. Depending on the result of the in-service area determination unit, the reception threshold A or a waiting time for the cell search may be adjusted, or the base station may be excluded from the cell search. Thus, the power consumption at the mobile device can be saved, and an appropriate in-service area determination can be made even when the minimum required quality level B has been changed.
