Spectrum Sharing Between A Surveillance Radar and Secondary Wi-Fi Networks
Farzad Hessar, Sumit Roy
Co-existence between unlicensed networks that share spectrum spatio-temporally with terrestrial (e.g. Air Traffic Control) and shipborne radars in 3-GHz band is attracting signific…
Real-Time Impulse Noise Suppression from Images Using an Efficient Weighted-Average Filtering
Hossein Hosseini, Farzad Hessar, Farokh Marvasti
In this paper, we propose a method for real-time high density impulse noise suppression from images. In our method, we first apply an impulse detector to identify the corrupted pix…
A GOST-like Blind Signature Scheme Based on Elliptic Curve Discrete Logarithm Problem
Hossein Hosseini, Behnam Bahrak, Farzad Hessar
In this paper, we propose a blind signature scheme and three practical educed schemes based on elliptic curve discrete logarithm problem. The proposed schemes impart the GOST signa…
Capacity Considerations for Secondary Networks in TV White Space
Farzad Hessar, Sumit Roy
The so-called `TV white spaces' (TVWS) - representing unused TV channels in any given location as the result of the transition to digital broadcasting - designated by U.S. Federal…
Minimum Energy Source Coding for Asymmetric Modulation with Application to RFID
Farzad Hessar, Sumit Roy
Minimum energy (ME) source coding is an effective technique for efficient communication with energy-constrained devices, such as sensor network nodes. In this paper, the principles…
