PROBLEM TO BE SOLVED: To provide a signal processing apparatus and signal processing method capable of suppressing an influence of an error while suppressing the number of bits.SOLUTION: The signal processing apparatus includes: a multiplier that obtains a mapping coefficient by multiplying a tap coefficient by 1/√2 and a converter that converts a digital input signal into a value of the tap coefficient×QPSK modulation point by multiplying the mapping coefficient by the digital input signal. |
