Average Bit Error Rate Calculation Based on Using Piecewise Spline Approximation
In this paper, an approximation of the average bit error rate (ABER) probability expression, standard performance measure of wireless transmission over fading channels using linear spline functions with corresponding number ...
Novel Composite Approximation for the Gaussian Q-Function
(Kaunas University of Technology, 2020-10-27)
This paper, by using Borjesson’s and Benitez’s approximation of Q-function, presents a novel and improved composite approximation of Q-function with wide applicability. The presented approach is very general and can be ...
Quantization of Weights of Neural Networks with Negligible Decreasing of Prediction Accuracy
(Kaunas University of Technology, 2021-09-24)
Quantization and compression of neural network parameters using the uniform scalar quantization is carried out in this paper. The attractiveness of the uniform scalar quantizer is reflected in a low complexity and relatively ...
Influence of zero boresight and non-zero boresight pointing error on BER FSO transmission over Malaga atmospheric channel
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2018-03-22)
In this paper, the influence of a zero and a non-zero boresight pointing errors on the performances of free-space optic transmission over the Málaga atmospheric turbulence channel is considered. Closed form expressions for ...
Binary Quantization Analysis of Neural Networks Weights on MNIST Dataset
(Kaunas University of Technology, 2021-08-23)
This paper considers the design of a binary scalar quantizer of Laplacian source and its application in compressed neural networks. The quantizer performance is investigated in a wide dynamic range of data variances, and ...
