Performance Assessment of WhatsApp and IMO on Android Operating System (Lollipop and KitKat) during VoIP calls using 3G or WiFi
R. C. de Oliveira, H. M. de Oliveira, R. A. Ramalho +1
This paper assesses the performance of mobile messaging and VoIP connections. We investigate the CPU usage of WhatsApp and IMO under different scenarios. This analysis also enabled…
A Flexible Implementation of a Matrix Laurent Series-Based 16-Point Fast Fourier and Hartley Transforms
R. C. de Oliveira, H. M. de Oliveira, R. M. Campello de Souza +1
This paper describes a flexible architecture for implementing a new fast computation of the discrete Fourier and Hartley transforms, which is based on a matrix Laurent series. The…
A Matrix Laurent Series-based Fast Fourier Transform for Blocklengths N=4 (mod 8)
H. M. de Oliveira, R. M. Campello de Souza, R. C. de Oliveira
General guidelines for a new fast computation of blocklength 8m+4 DFTs are presented, which is based on a Laurent series involving matrices. Results of non-trivial real multiplicat…
