  • Patent number: 8483331
    Abstract: A reception device calculates a radio quality in a downlink by using a plurality of pilot symbols transmitted from a base station. The reception device includes a correlation calculation unit and a radio quality calculation unit. The correlation calculation unit calculates a correlation value between a first pilot symbol and a second pilot symbol on a time axis or a correlation value there between on a frequency axis. If the correlation value obtained by the correlation calculation unit exceeds a predetermined threshold value, the radio quality calculation unit calculates a radio quality in the downlink by using a reception quality of the first pilot symbol and a reception quality of the second pilot symbol.

  • Patent number: 8295332
    Abstract: 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.
