Communications using frequency bands in the millimeter waves range will play a key role in future generations of mobile networks. It will provide high data rates by exploiting a wide range of unlicensed spectrum available at very high carrier frequencies. The prevailing challenge at high frequencies is to mitigate the problems of large path loss and link blockage. Highly directional beams are expected to overcome this challenge. Therefore, in this paper we derive the analytical computation of the coverage probability for a given beam. We develop a beam based stochastic model of the coverage probability, which takes into account both line-of-sight and first-order non-line-of-sight reflections. We exploit stochastic geometry to model the scattering environment and we provide a closed form expression of the coverage probability for any given beam. The results are validated numerically in order to assess the accuracy of the model.

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 ...
