Cellular base stations (BTS) and microwave relays have detached LNA stages located up in the aerial tower in order to mitigate NF degradation from pre-LNA cable loss. In the BTS architecture, the LNA stage is preceded by a transmit-receive (Tx-Rx) diplexer for duplexing a common aerial and by an interference fi lter for preventing out-ofband blocking or desensitization. However, both duplexer a...

Commercial advertising is the main source of income for TV channels and allocation of advertising time slots for maximizing broadcasting revenues is the major problem faced by TV channel planners. In this paper, the problem of scheduling advertisements on prime-time of a TV channel is considered. The problem is formulated as a multi-unit combinatorial auction based mathematical model. This is a...

Physical-layer network coding (PLNC) has the ability to drastically improve the throughput of multi-source wireless communication systems. In this paper, we focus on the problem of channel tracking in a Decode-and-Forward (DF) OFDM PLNC system. We proposed a Kalman Filter-based algorithm for tracking the frequency/time fading channel in this system. Tracking of the channel is performed in the t...

This paper presents a new approach for the channel capacity calculation of a multi-relay multi-hop communication system. For the channel model based on Markov chains theory, the exact formula for the channel capacity, which is expressed as a function of packet error rate and number of relays, is derived. The expression of the overall packet error rate is derived in its closed form. The presente...

Combiner and Stacked Generalization are two very similar meta-learning methods that combine predictions of multiple classiiers to improve accuracy of any single classiier. In this paper, we compare stacked generalization and combiner from the perspective of training eeciency versus accuracy. We show that both methods improve the accuracy of any single classiier roughly at an equivalent level. M...
