Abstract
A receiver ( ) for a wireless telecommunications system that provides relatively wideband signal processing of received signals without increased signal distortion so that multiple received signals can be simultaneously processed. The receiver ( ) includes a specialized LNA ( ), frequency down-converter ( ) and ADC ( ) to perform the wideband signal processing while maintaining receiver performance. A specialized digital channelizer ( ) is included in the receiver ( ) that receives the digital signal from the ADC ( ), and separates the signals into the multiple channels. In one embodiment, the frequency down-conversion is performed in a single down-conversion process, and the ADC ( ) employs delta-sigma processing to provide digital conversion over the complete frequency band.
