    摘要： A first digital signal sequence including I and Q digital signal sequences is obtained, the first digital signal sequence being obtained by multiplying each bit of an I-sequence and a Q-sequence in a digital signal sequence system by a first code among codes constituting n-th order (n is an integer) orthogonal codes. A second digital signal sequence is obtained by multiplying I and Q digital signal sequences by a first coefficient greater than 1, the I and Q digital signal sequences being obtained by multiplying each of the bits in the I-sequence and the Q-sequence in the digital signal sequence system by a first code among codes constituting 2n-th order orthogonal codes. The first digital signal sequence and the second digital signal sequence are added on a bit-by-bit basis to create one digital signal sequence, and the one digital signal sequence is transmitted from a single antenna.

    摘要： A MIMO communication method of performing MIMO communication between a base station having a plurality of antennas and each of a plurality of terminals covered by the base station using uplink data slots and downlink data slots that are alternately placed on a time axis. The method includes, in the base station, despreading a received signal that is transmitted from each of the plurality of terminals demodulating the transmission data transmitted from a respective terminal on the basis of the value of the estimated channel; decoding a received signal included in the uplink data slots, estimating a current channel between each of all antennas of the base station and the respective terminal; and comparing the stored value of the estimated channel with a value of the estimated current channel and updating the stored value of the estimated channel to the value of the estimated current channel.

    摘要： To suppress noise generation in a wide band and to suppress a clock speed from being increased in a sigma-delta modulation apparatus and a sigma-delta modulation power amplifier. A sigma-delta modulator creates a sigma-delta modulated signal for a digital output from a digital modulator, according to a clock given in advance. A threshold comparator indexes a portion in which the level of a digital output from the digital modulator is higher than a predetermined threshold and sends the resulting output. A replacing unit replaces the indexed portion with an output from a corresponding thinning unit. A filter unit performs band elimination filter processing on an output from the replacing unit and a digital-to-analog converter (D/A) performs digital-to-analog conversion on an output from the filter unit.
