With the advent of massive MIMO and mmWave, Antenna selection is the new frontier in hybrid beamforming employed in 5G base stations. Tele-operators are reworking on the components while upgrading to 5G where the antenna is a last-mile device. The burden on the physical layer not only demands smart and adaptive antennas but also an intelligent antenna selection mechanism to reduce power consumption...
The exponentially demand of Quality of Service (QoS) communication has made wireless communication as an inevitable technologies. Amongst major at hand technologies, Wireless Sensor Network (WSN) has been found an a potential solution to meet major real-world requirements, including monitoring and control, surveillance, healthcare, traffic surveillance and defence systems. Facilitating QoS demands,...
Channel Equalization in Telecommunication is the process of removal of any distortions that have incurred when any signal is transmitted through any channel. In this paper pilot based channel equalization using EKF(Extended Kalman Filter) for Rayleigh fading channel model is proposed. Using the pilot bits and the training sequences the channel state information is obtained, which is used to effectively...
Channel Equalization in Telecommunication is the process of removal of any distortions that have incurred when any signal is transmitted through any channel. In this paper pilot aided non linear channel equalization using UKF(Unscended Kalman Filter) for IEEE 802.16e Pedestrian A channel model is proposed. Using the pilot bits and the training sequences the channel state information is obtained, which...
The tremendous growth of broadcast and multicast traffic applications (audio, video, IPTV, teleconferencing etc) over the internet has created an imperative demand for high performance switches. Various switching architectures have been proposed for multicast traffic support. A Digital Cross Connect (DCS) is a crossbar-based switching device and has been considered the most suitable architecture because...
In this paper Extended Kalman Filter(EKF)is implemented with the Superposition Coded Modulation(SCM) scheme. For time varying Rayleigh fast fading channel environment an Extended Kalman filtering algorithm is proposed. The Rayleigh fading channel is approximated to be a Jakes Process and modeled as Autoregressive model. With the utilization of training sequences and fundamental channel model this...
A networking and communications revolution led by internet based technologies has caused intensive research in the domain of switching fabrics. The available Digital Cross Connects (DCS) IP cores requires lot of reengineering and recurrent engineering to customize them for any application and also are implemented through complex software algorithms which are expensive to develop and maintain. We proposes...
In this work, we analyzed channel estimation for SCM-OFDM system using Compressive sensing technique on frequency-selective multipath channel. The pilot aid based channel estimation techniques which uses training sequence are bandwidth inefficient. Compressive sensing is a bandwidth efficient technique in which only fewer pilots are used to estimate channel state information. The simulation result...
Underwater acoustic (UWA) transmission schemes are an interesting area of communication research, in which achieving high data rate, low latency and high throughput is challenging task. In this paper, we trying to provide a survey on various efficient techniques which that includes channel estimation, channel equalization and efficient modulation schemes to achieve high data rate in the receiver using...
The demand for the design and implementation of efficient crossbar arbiters has raised due to advancement in network-on-chip communication. The function of arbiters is to resolve contention among different i/o ports accessing a common resource. Digital circuits such as multiplexers are building blocks for the implementation of such arbiters in order to provide the best connectivity. The major challenge...
