Diversity Order in ISI Channels with Single-Carrier Frequency-Domain Equalizers
Ali Tajer, Aria Nosratinia
This paper analyzes the diversity gain achieved by single-carrier frequency-domain equalizer (SC-FDE) in frequency selective channels, and uncovers the interplay between diversity…
Beamforming and Rate Allocation in MISO Cognitive Radio Networks
Ali Tajer, Narayan Prasad, Xiaodong Wang
We consider decentralized multi-antenna cognitive radio networks where secondary (cognitive) users are granted simultaneous spectrum access along with license-holding (primary) use…
Optimal Joint Target Detection and Parameter Estimation By MIMO Radar
Ali Tajer, Guido H. Jajamovich, Xiaodong Wang +1
We consider multiple-input multiple-output (MIMO) radar systems with widely-spaced antennas. Such antenna configuration facilitates capturing the inherent diversity gain due to ind…
Beacon-Assisted Spectrum Access with Cooperative Cognitive Transmitter and Receiver
Ali Tajer, Xiaodong Wang
Spectrum access is an important function of cognitive radios for detecting and utilizing spectrum holes without interfering with the legacy systems. In this paper we propose novel…
