Quadrature receiver sampling architecture. A signal ADC performs analog to digital conversion for both I and Q streams. An analog MUX selects the appropriate I and the Q baseband analog input streams for input to the ADC at the appropriate time. A digital filter may also be employed to compensate for any introduced delay between the samples of the I and Q channel when seeking to recover the symbols that have been transmitted to a communication receiver that employs this quadrature receiver architecture and/or signal processing. In one embodiment, if an ADC is clocked at a rate of substantially twice the sample rate of the I and Q channels, there will be a one-half sample clock delay between the digital I and digital Q data at the output of the ADC. This delay is then removed before the demodulator processes the input signals to recover the transmitted symbols.
