Low Complexity Energy Detection for Spectrum Sensing with Random Arrivals of Primary Users

Due to random arrivals of primary user signals, the timing misalignment issue should be considered for spectrum sensing in cognitive radio (CR) systems, such as CR based femtocell networks. To deal with this issue, two approaches were recommended in the literature, including Bayesian and generalized likelihood ratio test (GLRT) detectors. However, Bayesian test requires perfect knowledge […]

Design of Thermally Poled Twin-Core Fiber Coupler With Electrical Tunability

Tunable coupler based on thermally poled twin-core fiber (TCF) with a hole-core-core-hole configuration was proposed in this letter. The thermal poling process therein was investigated based on the 2-D charge dynamics model. Effective χ(2) in the twin-cores pointing toward opposite directions were introduced. By subjecting the poled TCF to modulating voltage, the tunability of coupling ratio […]

Genetically Engineered Bacteria-Based BioTransceivers for Molecular Communication

Molecular Communication (MC) is a nano-scale communication paradigm where the information is carried by molecular signals. To establish information transmission using molecules, biological nanomachines can be utilized as transmitters and receivers. A bacteria can be programmed as a biotransceiver by modifying their genetic code to implement biological circuits. In this paper, genetically engineered bacteria-based biotransceivers […]

Cost-Effective Authentic and Anonymous Data Sharing with Forward Security

Data sharing has never been easier with the advances of cloud computing, and an accurate analysis on the shared data provides an array of benefits to both the society and individuals. Data sharing with a large number of participants must take into account several issues, including efficiency, data integrity and privacy of data owner. Ring […]

Understanding Taxi Service Strategies From Taxi GPS Traces

Taxi service strategies, as the crowd intelligence of massive taxi drivers, are hidden in their historical time-stamped GPS traces. Mining GPS traces to understand the service strategies of skilled taxi drivers can benefit the drivers themselves, passengers, and city planners in a number of ways. This paper intends to uncover the efficient and inefficient taxi […]

Artificial Noise Assisted Secure Transmission under Training and Feedback

This paper proposes a framework for the artificial noise assisted secure transmission in multiple-input, multipleoutput, multiple antenna eavesdropper (MIMOME) wiretap channels in frequency-division duplexed (FDD) systems. We focus on a practical scenario that only the eavesdroppers’ channel distribution information (CDI) is available and the imperfect channel state information (CSI) of the legitimate receiver is acquired […]

Zone 2 distance protection coordination with distribution feeder protection

In recent years, renewable energy generators have been widely promoted in Ontario to offset their polluting counterparts. Due to connection cost of these generations, most of the renewable generation stations are connected to Hydro One transmission system at nearby HV transmission lines. However, the direct connections of the generation on the transmission line result in […]

Design and optimization of a shaped-beam ka-band substrate integrated waveguide antenna array

Millimeter-wave antenna array Beam Forming Networks in Substrate Integrated Waveguide (SIW) technology are an attractive alternative to the use of TEM transmission lines, such as microstrip or stripline. SIW allows reducing the transmission losses while maintaining low price and simple, yet accurate, fabrication of the Printed Circuit Board technology. However, SIW design has additional restrictions and limitations […]
