    Split MLSE Adaptive Equalization in Severely Faded Rayleigh MIMO Channels

    This paper presents an overview of adaptive equalization used in Multiple-Input-Multiple-Output (MIMO) wireless systems. In this paper, the authors consider two-user transmission over a Rayleigh frequency selective fading channel, in which the Channel State Information (CSI) is known by the receiver. Subject to an average transmit power constraint, they study...

    Artificial Neural Network Aided Retina Based Biometric Identification System

    Artificial Neural Network (ANN)s are efficient means of prediction, optimization and recognition. Retina is a unique biometric pattern that can be used as a part of a verification system. An ANN can be configured and trained to handle such variations observed in the texture of the retina. The specialty of...

    Optimal Route Selection Strategy for QoS Improvement

    An ad-hoc mobile network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. Ad-hoc nodes operating in a single path, single channel model might experience packet loss and high latency...

    Improving Localization Accuracy in Wireless Sensor Networks

    The most fundamental problem of wireless sensor networks is localization (finding the geographical location of the sensors). Most of the localization algorithms proposed for sensor networks are based on Sequential Monte Carlo (SMC) method. To achieve high accuracy in localization it requires high seed node density and it also suffers...

    Performance Evaluation of Relaying Schemes for Wireless Communication Systems

    The evaluation of MIMO (Multiple-Input Multiple-Output) Relay wireless system is carried out and compared against the performance of a SISO (Single-Input Single-Output) Relay wireless system. The encoding scheme used in MIMO is Alamouti coding and decoding is done by the Maximum Likelihood (ML) detector. A comparison is made between the...

    A Fuzzy Based Approach in Multihop Network

    The proposed system utilizes the concept of multi hop communication in Wireless Sensor Networks (WSNs). On the other hand, the single hop communication leads to more power dissipation in the nodes at the time of transmitting sensed data. The proposed system rectifies the above mentioned problem with the multi hop...
