  1. 1. FPGA Implementation of Flexible Interpolators and Decimators

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Dabbugottu VenkataVikram; [2013]
    Keywords : Interpolation; Decimation; Linear-phase FIR interpolation; VHDL implementation of interpolators and decimators;

    Abstract : The aim of this thesis is to implement flexible interpolators and decimators onField Programmable Gate Array (FPGA). Interpolators and decimators of differentwordlengths (WL) are implemented in VHDL. The Farrow structure is usedfor the realization of the polyphase components of the interpolation/decimationfilters.

  3. 2. VHDL Implementation of Flexible Frequency-Band Reallocation (FFBR) Network

    University essay from Institutionen för systemteknik

    Author : Abrar Hussain Shahid; [2011]
    Keywords : 20-channel FFBR network; 20-point FFT IFFT; complex multiplier; polyphase components; radix-2; radix-5;

    Abstract : In digital communication systems, satellites give us world wide services. These satellites should effectively use the available bounded frequency spectrum and, therefore, to carry out flexible frequency-band reallocation (FFBR), on-board signal processing implementation on FFBR network is needed.
