This paper proposes a distributed implementation of spatial modulation (SM) using cognitive radios. In distributed spatial modulation (DSM), multiple relays form a virtual antenna array and assist a source to transmit its information to a destination. The source broadcasts its signal, which is independently demodulated by all the relays. Each of the relays then divides the received data in two parts:...
In this paper, a novel statistical approach for nonuniform sampling of a time-limited signal is proposed. Based on dynamic range, the signal is divided uniformly in equal intervals which constitute coarse partition. Then, total number of samples is nonuniformly distributed among the intervals of coarse partition leading to nonuniform sampling. The problem for nonuniform allocation of samples within...
This paper proposes the revamp of architecture of an eNodeB (eNB) for 5G cellular communication networks capable of opening up the crunched spectrum resources. We have developed a novel priority driven Resource Block (RB) handoff algorithm for Full-Duplex Multi-User MIMO communication, where the eNB creates beams for establishing communication links. The use of Full-Duplex operation enables simultaneous...
In this paper, we have proposed a cost effective method for rapid restoration of wireless connectivity in disaster hit areas, which face large scale failure of wireless infrastructure. This method includes setting of a reconfigurable Base Transceiver Station (BTS) based on Software Defined Radio (SDR) technology. The setup covers the drawbacks of existing methods for establishing connectivity in disaster...
This paper proposes the architecture of a cognitive base station for 4G cellular communication networks. We have developed a novel priority driven spectrum handoff technique for Multi-User MIMO communication, where the base station creates beams for establishing communication links. Adaptive beamforming methods along with DoA have been used to dynamically create a beam toward the intended receiver...
