In this paper, a method to identify sudden cardiac arrest is described based on the Pan-Tompkins Algorithm. Sudden cardiac arrest (SCA) is a condition in which the heart suddenly and unexpectedly stops beating. Sudden cardiac death occurs when the heart's electrical system malfunctions. The SCA happens, when blood stops flowing to the brain and other vital(More)
Segmentation plays a vital role in extracting information from medical images. Segmentation is the process of partitioning the image into distinct regions. Magnetic resonance imaging is used to extract images of soft tissues of human body. It is used to analyze the human organs without the need for surgery. Generally MRI images contain a significant amount(More)
Topology control in wireless sensor networks helps to lower node energy consumption by reducing transmission power and by confining interference, collisions and consequently retransmissions. Decrease in node energy consumption implies probability of increasing network lifetime. In this paper, firs popular topology control algorithms are used for analyzing(More)
In this paper we consider a performance index balancing outage probability for the overall cooperative system performance. The two approaches are used to estimate and optimize the value of the performance index, and the cooperative formation control is applied to move the mobile agents to achieve the optimal outage probability solution by using only the(More)
In this paper, Long Term Evolution (LTE) Cellular networks provides higher bit rates and consequently higher spectral efficiencies. Quadrature Amplitude Modulation has been adopted by most wireless communication standards such as Long Term Evolution (LTE). We analyses the Bit error rate (BER) of M-ary QAM in both multipath fading channels such as Rayleigh(More)
In this paper, we analysis the performance of Multiuser Multiple input Multiple output (MU-MIMO) Schemes in Long term evolution (LTE). As the performance metric, Block error rate and throughput are evaluated in terms of Signal to Noise Ratio (SNR) for different MIMO Schemes defined as in LTE. To achieve the high throughput required by the downlink LTE(More)
In this paper, presents interference suppression using a Space Time Block Coding-Subband Adaptive Array (STBC-SBAA) for uplink W-CDMA system over frequency selective fading channel is presented. The proposed scheme utilizes W-CDMA system with STBC and a receive array antenna with SBAA processing at the receiver. The received signal is converted into the(More)
The main goal of this paper is to understand the effects of frequency offset on orthogonal frequency division multiplexing (OFDM) systems and to present frequency offset estimation techniques so that we can correct for their effects. The performance of each technique is compared under various conditions. The performance of the estimators is presented in(More)
Higher the data rates and spectrum efficiency of wireless mobile communications have been significantly improved over the last decade, such as 3GPP Long-Term Evolution (LTE) and terrestrial digital TV broadcasting which are sophisticatedly developed using OFDM. Orthogonal frequency division multiplexing (OFDM) is a modulation technique that achieves high(More)
