We use 3-D ray tracing to evaluate the performance of millimeter wave (mmWave) cellular in a realistic model of MetLife stadium, NJ, USA. We model thousands of human blockages using the dielectric properties at 28GHz. Using this setup, we contrast the coverage and capacity performance with and without human blockages. Our study highlights that incorporating human models is essential for performance evaluation and also for deployment choice. We study the scaling in achievable data rates of three dense deployments in the stadium, and conclude that meeting the minimum 100 Mbps 5G requirement in stadiums can be challenging with a unicast mode of transmission. Broadcasting popular content in conjunction with a multiplexed unicast mode can provide minimum 100 Mbps rate for the broadcasted content.

Fair Dynamic Spectrum Management for QRD-Based Precoding with User Encoding Ordering in Downstream G.fast Transmission

In next generation DSL networks such as G.fast, employing discrete multi-tone transmission in high frequencies up to 212 MHz, the crosstalk among lines reaches very high levels. To precompensate the crosstalk in downstream transmission, QRD-based precoding has been proposed as a near-optimal dynamic spectrum management (DSM) technique. However, the performance ...

Practical Mitigation of Passive Intermodulation in Microstrip Circuits

This paper presents new experimental evidence and a novel practical approach for mitigation of passive intermodulation (PIM) in microstrip circuits fabricated on commercial printed circuit board laminates. The mechanisms of distributed PIM in microstrip circuits are reviewed and a phenomenology of PIM generation due to locally enhanced electromagnetic fields at ...

Efficient Cooperative HARQ for Multi-Source Multi-Relay Wireless Networks

In this paper, we compare the performance of three different cooperative Hybrid Automatic Repeat reQuest (HARQ) protocols for slow-fading half-duplex orthogonal multiple access multiple relay channel. Channel State Information (CSI) is available at the receiving side of each link only. Time Division Multiplexing is assumed, where each orthogonal transmission occurs ...
