A normal home environment consists of various wireless technologies, in particular WiFi and ZigBee, which usually operate in the ISM 2.4-GHz band. In addition, some of the home appliances (e.g., a microwave oven) may operate in this crowded ISM band. WiFi-based, ZigBee-based devices and home appliances operating at the same frequency and physical space can cause harmful interference to one another,...
In a home environment, a Smart Grid Home Area Network (SG-HAN) platform facilitates collection and delivery of power consumption information for load profiling and informed decisions on energy management. However, one of the main challenges in HAN is the overcrowded unlicensed 2.4-GHz ISM frequency band, occupied by several types of radio technologies such as ZigBee, Bluetooth, and WiFi. It is crucial...
Indoor downlink communication contributes to a large part of the data traffic generated in today's world. Enormous high data rate supporting devices are entering todays market. They demand for high rate wireless indoor coverage for their uninterrupted service. The main challenge lies in working with the existing wireless technologies while providing a future proof centralized optical fiber indoor...
Successive Interference Cancellation (SIC) is a well-known technique for enhancing wireless channel efficiency by allowing concurrent transmissions from multiple users. This multiuser detection technique is usually used in cellular systems. In this paper we adapt it to Radio-over-Fiber (RoF) system for the same purpose. Due to the similarity to using SIC in typical cellular networks, we mainly focus...
We consider the spectrum sharing of multiple cellular operators with independent infrastructures where their cells are overlapping in the same geographical area. Operators, which share their spectrum, need to deal with co-channel interference. We propose to use transmit-beamforming to reduce the inteference in the downlink transmission because beamforming requires minimum message passing between the...
