Interference cancellation is widely used in a number of application such as acoustic and speech signal processing, data communication, biological signal acquisition etc. Many papers with different approaches have been reported to cancel interferences in biosignals. This paper provides a survey of existing methods for interference cancellation in ECG signal, FECG signal, EEG signal, and EMG sign...
Crosstalk cancellation plays an important role in displaying binaural signals with loudspeakers. It aims to reproduce binaural signals at a listener’s ears via inverting acoustic transfer paths. The crosstalk cancellation filter should be updated in real time according to the head position. This demands high computational efficiency for a crosstalk cancellation algorithm. To reduce the computat...
Polar codes under successive cancellation decoding proposed by Ar{\i}kan provably achieve the symmetric capacity of any given binary-input discrete memoryless channel. The successive cancellation list decoder for polar codes was described by Tal and Vardy as a generalization of the successive cancellation decoder of Ar{\i}kan. The performance of the successive cancellation list decoder is encou...
Successive interference cancellation techniques have the potential to reduce the interference and therefore increase the capacity of cellular radio systems. In this work, we analyze a linear DS-CDMA receiver utilizing soft feedback interference cancellation. To be able to meet diverse QoS requirements, we introduce a power control scheme that takes into account heterogeneous service levels as w...
Co-site interference is a problem found everywhere from wireless systems and environmental sensors to military communications; it refers to the difficulty of extracting or detecting a weak signal in proximity to a strong transmitter. Traditional interference cancellation techniques are electronics-based and their performance is consequently bandwidthlimited; electronic interference cancellation...
Current surgical scheduling system has difficulties to handle unpredictable events or uncertainties. Source of uncertainties may come from the patient or the surgery itself, where several cases require immediate changes in data, such as when surgery delays or cancellation occurs on the same day. The study aimed to model the uncertainties for managing identified uncertainties during the continuo...
An urianibiguous definition of space is necessary before a n j attenipt niade to develop product or process niodels for concurrent engineering in the AEC Industry. The ambiguit;\, is the resur‘t of cliffererit and even conflicting approach to its definition in the various phases o f the buildirig life cjcle for direrent stukeholders, e.g. Architects, Eiigitieers, arid Brtii‘ditig Services Eiigi...
Active cancellation stealth is a significant developing direction in modern stealth technology field. In this paper, according to characteristics of linear frequency modulated (LFM) signal and nonlinear frequency modulated (NLFM) signal, the cancellation signal was designed. An important parameter called cancellaty which is used to measure the effect of cancellation is proposed. The basic theor...
The purpose of this audit was to find out the efficiency of our system in providing premedication to surgical day care patients. This audit was conducted in the Surgical Day Care (SDC) Unit of a University Hospital. All patients anaesthetised in the SDC unit on day care basis were included in this audit. Nursing notes and preoperative orders of all patients to be anaesthetised were checked to s...
BACKGROUND : Multidetector computed tomography (MDCT) is emerging as a powerful noninvasive diagnostic tool. The appropriate role of this technique in the preoperative evaluation of cardiovascular disease has yet to be fully defined. Atrial fibrillation is the most common sustained cardiac arrhythmia, and novel minimally invasive surgical techniques have been developed to treat this condition b...
