Abstract
One embodiment relates to a low intermediate frequency (IF) receiver. The low-IF receiver includes an analog front end that is configured to receive a modulated IQ data signal and provide an in-phase signal and a quadrature signal, where the in-phase signal is phase shifted by approximately 90° relative to the quadrature signal. The low-IF receiver further includes a digital processing block, and a single path that provides only one of the in-phase signal and the quadrature signal to the digital processing block. Other receivers and methods are also disclosed.
