Algorithms for reconstructing the images at close ranges and in a non homogeneous medium are described in this paper. Numerically calculated Green's functions are used to back propagate the observed signal to the image domain. Experimental results show that the image is better focused taking into account the inhomogeneous features of the propagation medium and that both breathing and heartbeat signals can be correctly extracted from the reconstructed images.","PeriodicalId":91990,"journal":{"name":"...

The feasibility of establishing a secure, unique and random key is investigated using a radio platform operating in the 2.4GHz ISM band. A low-complexity algorithm for establishing a symmetric encryption key tailored to the on-body propagation environment is proposed and justified. The algorithm uses the readily available radio signal strength indicator from existing packets going back and forth over the communication link and presents marginal system overheads. The secret bit sequences generated by the algorithm are evaluated for matching between the two communicating parties, mismatching with an eavesdropper placed on the body, and degree of randomness. It is shown that the algorithm generates long and highly random bit sequences which are perfectly matched between the legitimate communicating parties yet weakly matched with the eavesdropper's bit sequences.","PeriodicalId":91990,"journal":{"name":"...

The objective we have fixed was to introduce a parsimonious and computationally efficient method --- that can be ultimately incorporated on standard ECG recording devices --- to automatically localise points of interest and decide whether they are normal or not and, for abnormal points, assign them a given class of abnormality. The task we have already achieved is the localisation and identification of normal QRS complexes. Identification and localisation of other features, like premature atrial or ventricular beats, fibrillation, noise, bundle branch block beats, ectopic beats, etc. is in progress but the so far obtained preliminary results are very encouraging.","PeriodicalId":91990,"journal":{"name":"...

We found that the algorithms we implemented are more suitable for relatively homogeneous kidney tumors. For more heterogeneous tumors we should use more complicated segmentation techniques and some of these advanced techniques are discussed in this paper.","PeriodicalId":91990,"journal":{"name":"...

To take full advantage of such detectors, soft information is generated in the form of Log-Likelihood Ratios (LLRs) using a Bayesian estimator of phase of the signal pulse which is used to carry the information. We achieved significant reduction in the residual Bit Error Rate (BER) and Frame Error Rate (FER) using LDPC codes in the information reconciliation process. In this paper we explore the limits of the achievable performance gains when using photon counting detectors as compared to the case when such detectors are not available. To this end, we find the classical capacity of the Bayesian inference channel clearly showing the potential gains that photon counting detectors can provide in the context of a realistic cost-effective scheme from an implementation point of view. While there are binary communication schemes that can achieve a higher capacity for a given mean photon count at the receiver compared to the scheme presented here (e.g., the Dolinar receiver), most such schemes are complex and at times unrealistic from an implementation point of view.","PeriodicalId":91990,"journal":{"name":"...

The proposed WBAN consists of wearable sensor nodes which communicate with a coordinator node using a UWB transmitter and receive a feedback from the coordinator using a narrowband receiver. Advantages of using a narrowband signal instead of a UWB signal for the feedback path are discussed. The proposed MAC (Medium Access Control) protocol is based on IEEE 802.15.4/4a beacon enabled star topology. Performance is analyzed by varying the number of sensors. A comparison is given between suggested MAC protocol, which uses both slotted ALOHA and GTS, and a protocol totally based on slotted ALOHA.","PeriodicalId":91990,"journal":{"name":"...
