    Abstract: A communications system includes a first reception device and a transmission device. The transmission device includes a modulator operable to modulate a plurality of subcarriers using a signal series obtained by multiplexing a first signal series to be transmitted to the first reception device and a second signal series to be transmitted to a plurality of reception devices including the first reception device in a communications area of the transmission device and a transmitter operable to transmit the modulation signals. The first reception device includes a demodulator operable to regenerate the first signal series and the second signal series.

    Abstract: An n-bit binary value corresponding to an amount of phase shift d is assigned to an SREG, and a shift operation is performed. An n-bit vector value corresponding to a decimal value “1” is assigned to an LAT as an initial value. Thereafter, the input from an SW is sequentially stored. An MUL performs a square operation within a Galois field GF (2n) for the output of the LAT. A DBL performs a double operation within the Galois field GF (2n) for the output of the MUL. The SW selects either of the outputs of the MUL and the DBL according to the output value from the MSB side of the SREG. After the shift operation and the latch operation are performed a number of times n, the n-bit output of the LAT is output as respective phase shift coefficients b0 through bn−1.
