Abstract: Passive polyphase filter and first order active polyphase filter building blocks have been commonly used in the image reject downconverter. However, to operate in a wideband system and to ...
While most articles in this section discuss the reprogramming of graphics processors, other large arrays of processing elements are available as standard-product ICs for other applications. In some ...
Digital upconverters (DUCs) and digital downconverters (DDCs) are important components of every modern wireless base station design. While many DUC and DDC designs are available, there is a clear call ...
Before we proceed, let's quickly review our filter bank example. Our example, shown in Figure 1, is a size 16 DFT filter bank. The color scheme shows the sample rate change where a 16 MHz input sample ...
RF Engines is offering high speed polyphase discrete Fourier transform (DFT) cores for DSP filters. According to the Isle of Wight-based DSP specialist, polyphase DFTs provide high quality filter ...
The polyphase channelizer [1] down-converts simultaneously a set of frequency-division multiplexed (FDM) channels carried in a single data stream using an efficient approach based on digital signal ...
Polyphase filtering designs for FPGA provides performance boost for DSTO’s advanced receiver design. April 10, 2006 -- RF Engines (RFEL), the experts in signal processing for FPGA, have been awarded ...
