Despite standardization efforts, cardiac implantable electronic devices (CIED) report atrial fibrillation (AF) episodes differently across device manufacturers. Similarly, traditional rhythm management (CRM) protocols have failed to standardize physician-indicated AF. Thus, few studies characterized the frequency and accuracy of device-indicated This study quantified compared physician- (‘true’...

This paper evaluates the performance of differential modulation applied to the 3GPP UMTS Long Term Evolution downlink. With differential modulation, reference symbols for channel estimation are no longer necessary, thus increasing the potential maximum spectral efficiency. We present two basic modulation schemes and compare their performance to the coherent detection employed in Long Term Evolu...

In this paper we consider reciever design for frequency hopping orthogonal frequency-division multiple access system [2]. We propose new demodultaion algorithm that can increase the number of simultaneous transmissions with the same bit error rate. This algoritm can use any statistic that can test equality of emprical distribution funcions. We have used Kolmogorov-Smirnov statistic in this pape...

In this paper, we propose a cognitive transmission scheme with the best relay selection in a multiple-relay cognitive radio network to improve the secondary transmission performance while guaranteeing the quality-of-service (QoS) of the primary transmissions. We derive the closed-form expression of outage probability for the secondary transmissions, called Secondary outage probability, with the...

We undertake a systematic experimental study of the effects of concurrent packet transmissions in low-power wireless networks. Our measurements, conducted with Mica2 motes equipped with CC1000 radios, confirm that guaranteeing successful packet reception with high probability in the presence of concurrent transmissions requires that the signal-to-interference-plus-noise-ratio (SINR) exceed a cr...

Cooperative communication allows mult...

Pliable index coding considers a server with m messages, and n clients where each has as side information a subset of the messages. We seek to minimize the number of transmissions the server should make, so that each client receives (any) one message she does not already have. Previous work has shown that the server can achieve this using O(log(n)) transmissions and needs at least Ω(log(n)) tra...
