In this paper, we propose a design of rectangular microstrip patch antenna (RMPA). The glass epoxy substrate with height 1.6mm and the dielectric constant is 4.4 is used. The half circular slot etched on the patch at the top right as DMS, two circular slots etched on the ground plane as DGS. The DGS helps in shifting the resonant frequency to desired(More)
Multiple Input Multiple Output (MIMO) has been remained in much importance in recent past because of high capacity gain over a single antenna system. In this article, analysis over the capacity of the MIMO channel systems with spatial channel has been considered when the channel state information (CSI) is considered imperfect or partial. The dynamic CSI(More)
Semiblind channel estimation method provides the best trade-off in terms of bandwidth overhead, computational complexity and latency. The result after using multiple input multiple output (MIMO) systems shows higher data rate and longer transmit range without any requirement for additional bandwidth or transmit power. This paper presents the detailed(More)
Multiple Input Multiple Output (MIMO) antenna systems are being given much attention to provide high capacity with less bandwidth requirement. In this paper, some channel estimation techniques have been tried to implement with the adaptive semiblind channel estimation scheme using less requirement of pilot symbols similar to as in the case of the estimating(More)
The sensor networks like mobile sensor networks or the network that are built in a hurry are deployed in whimsical and undersigned configuration. For this reason, the sensor in such a network may become eventually adjacent to any other sensor in the network. In order to make a communication between every pair of adjacent sensors, in a secure way in such an(More)
The Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation technique becomes very popular because of its advance used in VLSI. Today it is used in many wireless standards such as WLAN, DAB and ETSI Hiperlan/2.In wireless communication system multi path propagation impairments can be reduce the error rate performance of the system. In(More)
This paper describes the design of the log periodically scaled microstrip patch antenna. The novelty of this antenna structure is a combination of a number of patch elements to create a log periodic array with modest bandwidth. The radiating element is a square patch antenna. The input impedance of the patch is adjusted to the probe feed and matched at(More)
Abstract-This paper presents a new way to realize the dynamic model of MIMO channel in presence of m-Nakagami fading. The dynamic model is compared with the static model of MIMO channel and the performance analysis of SISO, SIMO, MISO and MIMO systems is evaluated in presence of m-Nakagami distribution. All the results are plotted between signal to noise(More)
