A Wide Band IF Digital Platform
Peng Bo · Modern Electronics Technique · 2010
In order to solve the problems that the wide band intermediate frequency signal can′t be processed in the field of software radio timely,several key technologies and basic theories in the field of software radio focused on digital intermediate frequency technology are studied and discussed.An intermediate frequency digital processing platform built on CPCI architecture is designed and realized,the theory of the platform and the principle scheme are presented.With the signal of Motorola RF radio,the platform is validated by digital down frequency conversion and orthogonal FM demodulation on the actual signal.
