Least-Squares Design of Chromatic Dispersion Compensation FIR Filters Realized with Overlap-Save Processing
Oscar Gustafsson, Cheolyong Bae, Hakan Johansson
A design method for chromatic dispersion compensation filters realized using overlap-save processing in the frequency domain is proposed. Based on the idea to use the values that a…
Low-Complexity Memoryless Linearizer for Analog-to-Digital Interfaces
Deijany Rodriguez Linares, Håkan Johansson
This paper introduces a low-complexity memoryless linearizer for suppression of distortion in analog-to-digital interfaces. It is inspired by neural networks, but has a substantial…
On Frequency-Domain Implementation of Digital FIR Filters Using Overlap-Add and Overlap-Save Techniques
Hakan Johansson, Oscar Gustafsson
In this paper, new insights in frequency-domain implementations of digital finite-length impulse response filtering (linear convolution) using overlap-add and overlap-save techniqu…
Optimal Least-Squares Estimator and Precoder for Energy Beamforming over IQ-Impaired Channels
Deepak Mishra, Håkan Johansson
Usage of low-cost hardware in large antenna arrays and low-power wireless devices in Internet-of-Things (IoT) has led to the degradation of practical beamforming gains due to the u…
