This paper presents design and implementation of radio frequency quadrature modulator using multi-port network. The modulator utilizes Schottky diodes as high-speed variable impedance loads controlled by baseband data. The reflection coefficients produced by these variable loads modulate the RF carrier in proportion to the baseband signals. The paper also demonstrates test bed for generating differential in-phase and quadrature-phase baseband signals corresponding to digital modulation scheme. The hardware is designed and fabricated for operating at center frequency of 2 GHz. The results show successful modulation of 20 MHz LTE signal using 16 QAM data.

In this date to improve the fuel economy and get less emission, Hybrid Electric Vehicle (HEV) is developed. Energy management system has been developed where we can exploit the operating points of both the electrical system and the internal combustion engine. Typical power-split HEV model is built in this paper. To improve the tracking of the desired speed set points, Model Predictive control is used when subjected to the input and output constraints. The combination of both the series and parallel architecture is used in power split HEV to get different modes of operation. The combination and split of mechanical power generation is done with the use of planetary gear set. So near optimal fuel and energy management is done for the different modes of operation of the HEV with the implementation of Model Predictive Control.

In this work, we analyze the performance of decode-and-forward (DF) based dual hop free space optical (FSO) network utilizing M-ary differential phase shift keying (DPSK) signals under the combined impact of K-distributed atmospheric turbulence and misalignment error (ME). For the considered differential dual-hop FSO network, we derive the closed form expression for the average symbol error rate (SER) and outage probability (OP). We also perform the asymptotic outage analysis in order to obtain the diversity order analytically. Further, we also investigate the effect of different power allocation schemes on SER and OP by utilizing power distribution parameter. The simulation results validate all the derived analytical results.

The main aim of this research is to design a diplexer for 5G communications as proposed by TRAI 3.4 GHz to 3.6 GHz. The device consists of Wilkinson power divider, Band Pass Filters (BPF) with 20 MHz bandwidth. Filters and power combiners are realized with center frequency of the band (3.5 GHz). Uplink frequency choosen is 3.41 to 3.49 GHz and downlink frequency choosen is 3.51–3.59 GHz. In this device the two band pass filtering structures (for both uplink and downlink) are joined by a three port junction. The diplexer design is done by dividing the structure in two parts, to make the design more efficient and feasible. Eventually the whole diplexer is optimized to fit the desired specifications. In this paper band pass filters are designed using coupled lines, short circuited stubs and also with capacitive coupled resonators. Performance of the diplexer is compared among all three filter configurations.

In order to perceive the challenging goals set for 5G, a significant amount of future network performance improvements will be established by network infrastructure densification with increase in the density of operator deployed infrastructure elements. The number of operator deployed serving/access nodes will densify in such a manner that it will be comparable to or even transcend the density of user equipments (UEs) taking us forward to the new paradigm of Ultra-dense network (UDN). In such a backdrop, routing mechanisms are expected to be more objective oriented ensuring greater link reliability and enhancing quality of service of the dense network. The proposed work focuses on these aspects and shall cover the cooperative transmission mechanisms of routing in upcoming ultra dense wireless networks which shall be the arteries of data communication of the near future.
