Design of a sparse irregular array for beyond 5G base stations

New generations of mobile communications are much more demanding in order to provide critical real-time services and extremely fast connections that have become feasible with 5G. A wider spectrum is needed to achieve such high data rates and millimeter-wave frequencies are used for this purpose. Adaptive beamforming is applied at base stations...

Model-based Interference Mitigation for FMCW Radar System

With the increase in the number of radar systems/radio applications, FMCW radars currently face various interference problems which lead to wider noise band, rise in noise floor level and masking of weak targets. This thesis aims to eliminate different types of interference for FMCW radars.<br/>In this thesis, we propose a interference...

Interference cancellation techniques for low power wireless sensors

Non-coherent on-off keying (OOK) receivers are preferred in ultra low power (ULP) wireless devices as they consume less power when compared to receivers based on other modulation schemes. However, these devices are highly susceptible to co-channel interference (CCI). Therefore, interference cancellation (IC) techniques for ULP non-coherent OOK...

Spectrum Sharing among Cellular Operators from a Game Theoretical Cognitive and Cooperative Networking Perspective

The demand for wireless services and the need for high data-rates are growing rapidly. Future generation networks are expected to provide high data-rates in the order of 1Gbps in local area and 100Mbps in wide area. It is a challenge for operators to meet this rising demand for high data-rates as the radio-spectrum is an expensive and scarce...
