Sample signals P0(0) to P0 (N-1) are input for each symbol of a multiplexed transmission sample or transmission chip. The sum of a particular pair of sample signals (for example, a pair of P0 (0) and P0 (N/2)) is obtained by an adder (21) for each pair of sample signals, and a signal the power of which is halved by attenuating the sum with an attenuator is generated and output as a dispersion signal P1(N/2). Additionally, a difference between the pair of the sample signals is obtained by a subtractor (22), and a signal the power of which is halved by attenuating the difference with an attenuator (23) is generated and output as a dispersion signal P1(0). The dispersion signals Pl(0) and Pl(N/2) are made to respectively correspond to first and second subsymbols, which are configured by partitioning the symbol. |
