Abstract
A multiplexing scheme to select either an I component or a Q component for input to I channel and Q channel inputs of a baseband receiver. The selection of which of the I or Q component to place on the I channel input and which other to place on the Q channel input is based on, there being a correct relationship of the I and Q components received from a RF processing stage of a wireless communication device or if the I and Q components have incorrect relationship because they are interchanged.
