Relay Assisted Underlay Cognitive Radio Networks with Multiple Users
Lanwei Zhang, Rajitha Senanayake, Saman Atapattu +1
In this letter, we consider an underlay cognitive radio network assisted by dual-hop decode-and-forward (DF) relaying. For a general multi-user network, we adopt a max-min fairness…
Frequency Permutations for Joint Radar and Communications
Rajitha Senanayake, Peter Smith, Tian Han +3
This paper presents a new joint radar and communication technique based on the classical stepped frequency radar waveform. The randomization in the waveform, which is achieved by u…
Phase Modulated Communication with Low-Resolution ADCs
Samiru Gayan, Hazer Inaltekin, Rajitha Senanayake +1
This paper considers a low-resolution wireless communication system in which transmitted signals are corrupted by fading and additive noise. First, a universal lower bound on the a…
Low-Resolution Quantization in Phase Modulated Systems: Optimum Detectors and Error Rate Analysis
Samiru Gayan, Rajitha Senanayake, Hazer Inaltekin +1
This paper considers a wireless communication system with low-resolution quantizers, in which transmitted signals are corrupted by fading and additive noise. For such wireless syst…
