Title: Radio receiver
IPC: H04L27/38
Filed: 2001-11-06
Abstract: A radio receiver configurable to operate in either a low-IF or a zero-IF mode comprises a quadrature down-converter ( 108,110,112,114 ) for generating in-phase (I) and quadrature (Q) signals at an intermediate frequency and a complex filter ( 202 ) for performing image rejection filtering. One of the outputs (Q) of the filter ( 202 ) is terminated, the other (I) is passed to a non-complex ADC ( 206 ). The output from the ADC is processed digitally then a quadrature signal generator ( 212,214 ) generates quadrature-related IF signals which are passed to a down-converter ( 216,218 ) for conversion to baseband signals. By enabling analogue-to-digital conversion and channel filtering to be performed at IF on non-complex signals, significant power savings are possible. Further, the flexibility of the receiver is enhanced, enabling it to operate efficiently in both low-IF and zero-IF modes.
