In the area of cooperative and network coded communication that naturally arises from cooperation, which become increasingly important in wireless communications, the expected end-to-end bit error rate (BER) values are frequently required to compare the proposed coding, relaying, and decoding techniques. Instead of obtaining these values through time consuming Monte Carlo simulations, deriving the closed form expressions via approximations is also crucial. In this work, we make use of the sampling property of the Q-function, which we commonly face while dealing with the related expectation integrals, in order to derive the end-to-end BER expressions for a network coded system. Furthermore, we show that the obtained expressions well agree with the simulation results.

A diversity and coding gain analysis for the cooperative wireless communication channel under fading using sampling property of the Q-function İşbi̇rli̇kli̇ kablosuz haberleşmede sönümlemeli̇ kanal i̇çi̇n Q-fonksi̇yonunun örnekleme özelli̇ǧi̇nden yararlanan bi̇r çeşi̇tleme ve kodlama kazanci anali̇zi̇ Aktaş, Tuǧcan; Yılmaz, Ali Özgür; AKTAŞ, EMRE (2012-07-09) This work presents approximation methods that are used to identify Bit Error Rate (BER) expressions which are frequently utilized in investigation and comparison of performance for wireless communication systems in the literature. In this group of approximation methods, some expectation integrals, which are complicated to analyze and time-consuming to evaluate through Monte Carlo simulations, are handled. For this group of integrals, by using the sampling property of the Q-function under mid- and high- Sign...
Differential network coding in wireless networks Telsiz aǧlarda farksal aǧ kodlamasi Özdemir, Özgür; Yılmaz, Ali Özgür (2009-10-29) In this paper a three-terminal communication scenario where two users exchange information by employing differential binary modulation and network coding via a relay is considered. The transmission is divided into three slots in time where the first and second slots are allocated to the transmission of differential encoded data of the users. After demodulation, the relay broadcasts the bit-wise XOR-ed and differential encoded packet to the users in the third slot. The optimum detector and a simplified decis...
Evaluation of priority dependent and time scheduled MAC layer protocols for ad-hoc networks Erdeğer, İsmail; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2015) Ad-hoc networks have very unique features, such as dynamic topologies, relatively limited bandwidth and wireless signal propagation schemes, which present various challenges for wireless communication. In this thesis, control mechanisms for channel access scheduling and topology in ad-hoc networks are evaluated, which utilize the information from two-hop neighborhood to cope with the communication difficulties in ad-hoc networks. Channel assignment is one of the most important topics for ad-hoc networks. Ch...
Implementation and evaluation of a synchronous time-slotted medium access protocol for networked industrial embedded systems Gözcü, Ahmet Korhan; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2011) Dynamic Distributed Dependable Real-time Industrial communication Protocol family (D3RIP), has been proposed in the literature considering the periodic or event-based traffic characteristics of the industrial communication networks. D3RIP framework consists of two protocol families: Interface Layer (IL) protocol family, which is responsible for providing the accurate time-division multiple access (TDMA) on top of a shared-medium broadcast channel, and Coordination Layer (CL), which is defined to fulfill the...
Evaluation of Terahertz Channel in Data Centers MOLLAHASANİ, Shahram; Onur, Ertan (2016-04-29) Designing data center network topologies with the objective of minimizing cost, increasing bisection bandwidth and decreasing latency is a difficult problem. The solutions in the literature mainly concentrate on wired networks and minimizing wiring costs thereof. Only a few proposals address the benefit of employing wireless communications in data centers due to spectrum and bandwidth limitations of current wireless communication technologies. By using terahertz communication in a data center as a complemen...
