Ultra-Dense Networks: A New Look at the Proportional Fair Scheduler
Ming Ding, David Lopez Perez, Amir H. Jafari +2
In this paper, we theoretically study the proportional fair (PF) scheduler in the context of ultra-dense networks (UDNs). Analytical results are obtained for the coverage probabili…
Performance Evaluation of Spatial Complementary Code Keying Modulation in MIMO Systems
A. H. Jafari, T. O'Farrell
Spatial complementary code keying modulation (SCCKM) is proposed as a novel block coding modulation scheme. An input binary sequence is modulated based on the different lengths of…
Diversity Pulse Shaped Transmission in Ultra-Dense Small Cell Networks
Amir H. Jafari, Vijay Venkateswaran, David Lopez-Perez +1
In ultra-dense small cell networks, spatial multiplexing gain is a challenge because of the different propagation conditions. The channels associated with different transmitreceive…
Performance Impact of LOS and NLOS Transmissions in Dense Cellular Networks under Rician Fading
Amir H. Jafari, Ming Ding, David Lopez-Perez +1
In this paper, we analyse the performance of dense small cell network (SCNs). We derive analytical expressions for both their coverage probability and their area spectral efficienc…
Pulse Shaping Diversity to Enhance Throughput in Ultra-Dense Small Cell Networks
Amir H. Jafari, Vijay Venkateswaran, David Lopez-Perez +1
Spatial multiplexing (SM) gains in multiple input multiple output (MIMO) cellular networks are limited when used in combination with ultra-dense small cell networks. This limitatio…
Study on Scheduling Techniques for Ultra Dense Small Cell Networks
Amir H. Jafari, David Lopez-Perez, Ming Ding +1
The most promising approach to enhance network capacity for the next generation of wireless cellular networks (5G) is densification, which benefits from the extensive spatial reuse…
