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)
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)
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)
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)
