Digital down converters wifi

Digital up conversion is required when a signal is translated from baseband to intermediate frequency IF band. Digital down conversion happens when a signal is converted from intermediate frequency band to baseband.

DUCs and DDCs typically include frequency shifting using mixers, in addition to sampling rate conversion. This reference design was specifically tested for a WiMAX configuration. An IF sampling frequency of See additional license requirements below for details.

Issue Date Metadata Show full item record. Other Titles Digital front-end in wireless communications and broadcasting: circuits and signal processing. Abstract Digital conversion is a fundamental part of many digital radio systems, which include upconversion of the discrete baseband signal stream into a high-resolution radio signal at the transmitter, and down-conversion of a high-resolution radio signal back into a baseband signal at the receiver.

In this chapter, we cover the basics of digital conversion analog to digital and digital to analog , the functionality of digital up-converter and digital down-converter in relation to conversion between intermediate frequency and baseband with the emphasis on the implementation of the DDC and DUC for standard wireless communication systems.
