Reinforced concrete frame buildings with Open Ground Story (OGS) are one of the most common building configurations in urban habitat. These configurations are known to be vulnerable to seismic excitations, primarily due to the sudden loss in strength in the ground story and differential stiffness distribution throughout the structure. The differential stiffness distribution is attributed primar...

Non-Orthogonal Multiple Access (NOMA) has been proposed to enhance the Spectrum Efficiency (SE) and celledge capacity. This paper considers the massive Multi-Input Multi-Output (MIMO) with Non-Orthogonal Multiple Access (NOMA) encoding. The close-form expression of capacity of the massive MIMO with NOMA is given here. Apart from the previous Successive Interference Cancellation (SIC) method, th...

Cognitive Radio (CR) is promising technique for access of spectrum resources. The sensors deployed vast environmental area are in need of hundreds to thousands of sensor nodes which is mostly energy constrained and their batteries are not rechargeable in most Wireless Sensor Networks applications. A Cognitive Radio Sensor Network (CRSN) is defined as wireless sensor network equipped with cognit...

To solve the shortage defects of wireless spectrum source of Internet of things, an idle spectrum resources and immune sorting selection method based on the subjective and objective weight is proposed by using cognitive radio network technology. Firstly, the radio cognitive idle spectrum system is relied on to make the spectrum system modeling of Internet of things for the generation of objecti...

1 Electronics and Telecommunication, Pune University Cognitive Radio technology helps in designing wireless system for efficient deployment of radio spectrum with its sensing technique,self adaptation and spectrum sharing. Spectrum sharing is an effective method of alleviating the scarcity of radio spectrum problem by allowing unlicensed users (secondary users) to coexist with licensed users (p...

Cognitive Radio technology helps in designing wireless system for efficient deployment of radio spectrum with its sensing technique, self-adaptation and spectrum sharing. Spectrum sharing is an effective method of alleviating the scarcity of radio spectrum problem by allowing unlicensed users(secondary users) to coexist with licensed users (primary users) under the condition of protecting the l...

It has been shown that signature (multi-) sets that meet Welch’s lower bound on the total squared correlation (TSC), maximize the sum capacity of the synchronous code division multiple access (CDMA) channel with equal average input energy constraints. However, a signature set that is TSC-optimum (i.e. achieves the lower bound on TSC), doesn’t necessarily have a low cross-correlation spectrum. H...

We present a novel local optimum based power allocation approach for spectrum sharing in unlicensed frequency bands. The proposed technique is based on the idea of dividing the network in a number of smaller sub-networks or clusters. Sum capacity of each cluster is maximized subject to constraint on total power of each user in a cluster. On its turn each user in a cluster maximizes the sum capa...
