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 ...

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 ...

Abstract: This paper presents a strategy for successful polyphase-filter design for continuous-time quadrature bandpass sigma-delta (SigmaDelta) modulators. Based on a low-pass filter with a chain of ...

Abstract: Polyphase filters are an efficient solution for high image rejection and great accuracy quadrature generation in radio frequency (RF) receivers. Analytical modeling of passive polyphase ...

this includes gnuradio scripts and an I/Q file to understand polyphase filter banks. the flow graphs show the basic idea, and then lead up to the final polyphase method. the I/Q file has a Fs = 96KHz, ...

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 ...
