چکیده
In this paper we present arithmetic transformations of firstand second-order allpass sections for increased maximal sample rate. Also the implementation of a combined interpolator and decimator for an OFDM based communication system is presented. The arithmetic transformations were applied to the second-order allpass sections of the implemented filter, yielding a 40% increase of the maximal sample rate at the expense of a 10% increase of the core area. Finally, the design of a digital down converter for an array antenna radar system is presented.

Implementation of Narrow-band Lattice Wave Digital Filters
Recently, a filter structure for narrow-band filtering based on lattice wave digital filters was introduced. The structure has increased parallelism over the corresponding direct realization. In this paper, hardware implementation of the filter structure is discussed. The suggested approach uses bit-serial processing elements that are scheduled so that a maximally fast implementation is achieve...

In this paper arithmetic transformations for increased maximal sample rate of bit-parallel lattice wave digital filters implemented with carry-save arithmetic are proposed. The purpose is to increase the throughput in order to allow a reduction of the power consumption through supply voltage scaling. A lattice wave digital filter can be composed of firstand secondorder allpass sections which ar...
متن کاملMaximally Fast Scheduling of Bit-serial Lattice Wave Digital Filters Using Three-port Adaptor Allpass Sections
In this paper we show how to achieve a maximally fast lattice wave digital filter using three-port adaptor allpass sections. Using three-port adaptors may increase the maximal sampling rate with approximately 50% compared to using second-order Richards’ allpass sections. Only bitserial arithmetics is discussed in the paper, but the same ideas can be utilized for digit-serial and bit-parallel ar...
متن کاملArithmetic transformations for increased maximal sample rate of bit-parallel bireciprocal lattice wave digital filters
In this paper we propose an arithmetic transformation of firstorder allpass lattice wave digital filter sections implemented with bit-parallel, carry-save arithmetic which increases the maximum sample rate. Such filter sections are the critical component of bireciprocal lattice wave digital filters which are efficient filter structures for sample rate conversion with factors of two. The propose...
متن کاملImplementation of maximally fast ladder wave digital filters using a numerically equivalent state-space representation
Ladder Wave Digital Filters is a class of IIR digital filters derived from double resistively terminated ladder networks, which gives them good stability and low sensitivity to variations in the element values. An approach to design maximally fast bit-serial ladder wave digital filters is presented based on the numerically equivalent state-space representation of the signal-flow graph. An algor...
