Complementary signal mixing

摘要

A method of performing complementary mixing may include performing an exclusive OR (XOR) function with respect to an I-channel symbol based on an oscillator signal to produce an I-channel output signal with bits that alternate between the I-channel symbol and a complement of the I-channel symbol in response to the oscillator signal rising and falling. The method may also include performing the XOR function with respect to a Q-channel symbol based on the oscillator signal to produce a Q-channel output signal with bits that alternate between the Q-channel symbol and a complement of the Q-channel symbol in response to the oscillator signal. Further, the method may include combining the I-channel output signal and the Q-channel output signal based on adding operations performed with respect to an I-channel extra bit signal, a Q-channel extra bit signal, the I-channel output signal, and the Q-channel output signal to generate a complementary mixed signal.
