Coexistence Analysis between Radar and Cellular System in LoS Channel
Awais Khawar, Ahmed Abdelhadi, T. Charles Clancy
Sharing spectrum with incumbents such as radar systems is an attractive solution for cellular operators in order to meet the ever growing bandwidth requirements and ease the spectr…
Channel Modeling between Seaborne MIMO Radar and MIMO Cellular System
Awais Khawar, Ahmed Abdelhadi, T. Charles Clancy
Spectrum sharing between radars and cellular systems is an emerging area of research. In this paper, we model channel between a seaborne MIMO radar and MIMO cellular system. We mod…
Radar Precoder Design for Spectral Coexistence with Coordinated Multi-point (CoMP) System
Jasmin A. Mahal, Awais Khawar, Ahmed Abdelhadi +1
This paper details the design of precoders for a MIMO radar spectrally coexistent with a MIMO cellular network. We focus on a coordinated multi-point (CoMP) system where a cluster…
Target Detection Performance of Spectrum Sharing MIMO Radars
Awais Khawar, Ahmed Abdelhadi, T. Charles Clancy
Future wireless communication systems are envisioned to share radio frequency (RF) spectrum, with other services such as radars, in order to meet the growing spectrum demands. In t…
QPSK Waveform for MIMO Radar with Spectrum Sharing Constraints
Awais Khawar, Ahmed Abdelhadi, T. Charles Clancy
Multiple-input multiple-output (MIMO) radar is a relatively new concept in the field of radar signal processing. Many novel MIMO radar waveforms have been developed by considering…
On The Impact of Time-Varying Interference-Channel on the Spatial Approach of Spectrum Sharing between S-band Radar and Communication System
Awais Khawar, Ahmed Abdelhadi, T. Charles Clancy
Spectrum sharing is a new approach to solve the congestion problem in the RF spectrum. A spatial approach for spectrum sharing between a radar and a communication system was propos…
Optimal Downlink Power Allocation in Cellular Networks
Ahmed Abdelhadi, Awais Khawar, T. Charles Clancy
In this paper, we introduce a novel approach for power allocation in cellular networks. In our model, we use sigmoidal-like utility functions to represent different users' modulati…
