Patent ID: 7817744

Claim:
A radio communication apparatus that multiplexes first data and second data, the radio communication apparatus comprising: a dividing section that divides a modulated symbol of the first data into a first in-phase component and a first quadrature component and divides a modulated symbol of the second data into a second in-phase component and a second quadrature component; a converting section that converts the first in-phase component into a third quadrature component and converts the second quadrature component into a fourth in-phase component; a multiplexing section that performs multi-code multiplexing of the first quadrature component and the third quadrature component to obtain a first multiplexed signal, and performs multi-code multiplexing of the second in-phase component and the fourth in-phase component to obtain a second multiplexed signal; and a combining section that combines the first multiplexed signal and the second multiplexed signal to obtain a combined signal.
