摘要： Antenna received signals 101-1 to 101-n are input to weighting coefficient calculation section 103. Weighting coefficient calculation section 103 determines weighting coefficients so as to eliminate interference using antenna received signals 101-1 to 101-n and known signal and combines them into weighted/combined signal 107. Envelope variation detection section 116 detects variations in the envelope of the weighted/combined signal. Interference mixing time detection section 108 detects the interference mixing time from the output of envelope variation detection section 116. Envelope variation detection sections 117 to 119 detect envelope variations of the received signals. Combination system control section 113 switches switch section 114 so that the received signal with the least envelope variation may be output at the interference mixing time.

摘要： A storing device stores a plurality of remainder tables which respectively hold corresponding remainder information strings by using a plurality of unit information strings as indexes. A table looking-up device obtains a plurality of remainder information strings by partitioning a target information string, which is processed with a loop process performed once, into a plurality of unit information strings and by referring to the plurality of remainder tables with the use of the unit information strings as indexes. A calculating device calculates an exclusive OR of the obtained plurality of remainder information strings and the first information string of an unprocessed portion of an input information string. The table looking-up device repeats a reference of the plurality of remainder tables a predetermined number of times by using the obtained information string of the exclusive OR as a target information string in the next loop process.

摘要： In a base station, a received signal strength calculation unit calculates the received signal strength of data sent by wireless terminals. A scheduler re-allocates the wireless resource next to a wireless terminal that will cause the smallest change from the received signal strength of the currently allocated wireless terminal. The base station can receive data sent from the wireless terminals in such a manner that the received signal strength varies gradually, and degradation in quality of reception can be suppressed.
