In a heterogeneous wireless network environment always best connected concept requires the selection of an optimal access network. Selection of a non-optimal network can result in undesirable effects such as higher costs and poor service experience. In this paper an attempt is made to find a solution for network selection by using two multiple attribute(More)
Space -time block codes from orthogonal design have two advantages, namely, fast maximum - likelihood (ML) decoding and full diversity. Rate 1 real space -time codes (real orthogonal design) for multiple transmit antennas have been constructed from the real Hurwitz - Radon families, which also provides the rate ¿ complex space -time codes(complex orthogonal(More)
Energy Detection based Spectrum Sensing technique plays major role because of its low complexity. Performance of Energy detection based spectrum sensing of unknown signals can be achieved over Rayleigh fading channel by deriving its detection probability with and without considering diversity techniques. Detection probabilities versus average(More)
An equalization technique based on nonlinear Hammerstein type filters to combat the inter symbol interference (ISI) effect is proposed. This technique is nothing but nonlinear generalization of the linear equalizer. Linear frequency selective fading channels in presence of additive white Gaussian noise is considered using DPSK and QAM modulation techniques(More)
A complex orthogonal design that provides full diversity and full transmission rate for a space–time block code is not possible for more than two antennas. We design rate one codes which are quasi-orthogonal and provide partial diversity. The decoder of the proposed codes works with pairs of transmitted symbols instead of single symbols. A number of(More)
Removal of mandibular third molars for various reasons is one of the most frequently carried out procedures in oral surgery. Most of the surgeries are performed with minimal intra or postoperative difficulties. However, occasionally this common procedure can result in several complications. Purpose of the study was to analyse the incidence of postoperative(More)
In this automated world, the comfort over handling of any kind of device has become possibly the easiest factor everywhere, having the similar aspect of building comfort zone, a system is designed for the evolution of automation in gardening process. This paper proposes a novel gardening system with automates the working of garden tool in an efficient(More)
This article describes the treatment of an adult female with periodontally induced bone loss, excessive gingival display when smiling, vertical maxillary excess, a convex profile, a traumatic deep overbite, and severe lip incompetence. The therapy included four steps: (1) periodontal flap surgery and root planing with regular follow-ups; (2) leveling and(More)
