Closed-Form Least-Squares Design of Fast-Convolution Based Variable-Bandwidth FIR Filters
Oksana Moryakova, Håkan Johansson
This paper introduces a closed-form least-squares (LS) design approach for fast-convolution (FC) based variable-bandwidth (VBW) finite-impulse-response (FIR) filters. The proposed…
Efficient Computation of Time-Index Powered Weighted Sums Using Cascaded Accumulators
Deijany Rodriguez Linares, Oksana Moryakova, Håkan Johansson
This letter presents a novel approach for \mbox{efficiently} computing time-index powered weighted sums of the form using cascaded accumulators. Tradi…
Modeling, Analysis, and Optimization of Cascaded Power Amplifiers
Oksana Moryakova, Thomas Eriksson, Håkan Johansson
This paper deals with modeling, analysis, and optimization of power amplifiers (PAs) placed in a cascaded structure, particularly the effect of cascaded nonlinearities is studied b…
Joint Sampling Frequency Offset Estimation and Compensation Based on the Farrow Structure
Deijany Rodriguez Linares, Oksana Moryakova, Håkan Johansson
This paper introduces a sampling frequency offset (SFO) estimation method based on the Farrow structure, which is typically utilized for the SFO compensation and thereby enables a…
