A High Effective Architecture for Ultra-Wideband Digital Orthogonal Transform
Dongpo Zhang · Communication Countermeasures · 2006
The design of the high speed digital orthogonal transformer which architecture based on the digital channelization in frequency domain is introduced in this paper. By adopting the optimization algorithm of the digital transform and designing the filter banks properly, the proposed digital orthogonal transformer can broaden the effective processing bandwidth extremely while the application requirements is satisfied, however the calculation and hardware source can be reduced significantly. The high precise NCO is not needed in the digital orthogonal transformer. The realization of this transformer is profound for wideband digital receiver and real-time signal processing.
