Statistical Intercell Interference Modeling for Capacity-Coverage Tradeoff Analysis in Downlink Cellular Networks

open access: yes, 2014
Interference shapes the interplay between capacity and coverage in cellular networks. However, interference is non-deterministic and depends on various system and channel parameters including user scheduling, frequency reuse, and fading variations.

Ray-Based Modeling of Directional Millimeter-Wave V2V Transmissions in Highway Scenarios

open access: yesIEEE Access, 2020
Due to the need for larger bandwidth, future mobile networks may primarily operate over millimeter-wave (mmWave) bands. In this regard, one of the central research topics today is mmWave channel modeling.

Cancellation of Power Amplifier Induced Nonlinear Self-Interference in Full-Duplex Transceivers

open access: yes, 2014
Recently, full-duplex (FD) communications with simultaneous transmission and reception on the same channel has been proposed. The FD receiver, however, suffers from inevitable self-interference (SI) from the much more powerful transmit signal.

Bubble-Driven Inertial Micropump

open access: yes, 2012
The fundamental action of the bubble-driven inertial micropump is investigated. The pump has no moving parts and consists of a thermal resistor placed asymmetrically within a straight channel connecting two reservoirs.

Simulation and Analysis of Propagation Characteristics for Tunnel Train-Ground Communications at 1.4 and 40 GHz

open access: yesIEEE Access, 2019
This paper focuses on the analysis of propagation characteristics for train-ground communication (TGC) systems in tunnel scenarios at both low frequency and millimeter-wave (mmWave) bands, based on ray-tracing (RT) simulation.

Delay Constrained Throughput Analysis of a Correlated MIMO Wireless Channel

open access: yes, 2011
The maximum traffic arrival rate at the network for a given delay guarantee (delay constrained throughput) has been well studied for wired channels. However, few results are available for wireless channels, especially when multiple antennas are employed ...
