Cloud services are gaining popularity with times. Service level agreement (SLA) serves a basic understanding between the clients and cloud service providers (CSP). Ensuring secured and adequate service is a basic need of the customers. In this work a set of compliance parameters for cloud service level agreement is identified. A generic rule base is designed to empower the process with an automated...
In Virtual Antenna Array (VAA) based wireless system, knowledge of users' locations can help the transmitter to achieve interference avoidance by steering the main beam towards the intended recipient. In this work, the idea has been applied to licensed shared access (LSA) based cognitive radio (CR) environment where location aware beam-forming has been implemented on spatially modulated Generalized...
Generalized Frequency Division Multiplexing (GFDM) is a recently proposed multicarrier waveform which is being considered as one of the possible candidates for 5G wireless access technology. Key advantages of GFDM are flexibility and low spectral side-lobes which render it the ability of carrier aggregation and reduced adjacent channel interference. However due to its non-orthogonal nature GFDM suffers...
In this work, we propose a novel solution for a switched beamformer called the adjustable phased array system (APAS). By programming electronic switches, the implemented four‐antenna APAS circuit generates 12 phase‐shift angles that are multiples of
. Compared to the legacy
Butler matrix, the proposed APAS only needs one input port and four output ports and can provide more beam patterns...
