In this paper, an FPGA implementation in which packet synchronization is performed by transmitting pilot sequences will be explained. In addition, in order to recover the frequency offset between the frequencies of oscillators at the transmitter and the receiver, a PLL like structure is proposed.


Analysis of the performance of network coding using the sampling property of Q-function Ǎg Kodlama için q-fonksiyonun örnek alma özellǐginden yararlanarak başarim analizi

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 ...
The Development and hardware implementation of a dynamically reconfigurable and area optimized cyclic redundancy check architecture
Yurt, Özcan; Schmidt, Şenan Ece; Department of Electrical and Electronics Engineering (2013)
The Cyclic Redundancy Check (CRC) calculation for data communication protocols is implemented by hardware calculators in several systems due to increasing throughput requirements of data communication protocols. Furthermore CRC is employed in many small scale embedded systems with different types of data communication interfaces that are implemented on FPGA. Resource utilization of these systems is frequently a critical parameter with regards to cost. In many cases, limited logic units of an FPGA have to be...

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...
On the Carrier Frequency Offset Estimation for Frequency Hopping Burst Mode Mobile Radio
Güvensen, Gökhan Muzaffer; Tanık, Yalçın; Yılmaz, Ali Özgür (2010-11-03)
In this paper, we evaluate the Cramer-Rao bounds (CRB) for the estimation of the carrier frequency offset (CFO) for general QAM modulations with no knowledge of the transmitted sequence (blind operation) in frequency hopping (FH) based short burst mode mobile radios. We investigate the blind CFO estimation problem in FH based mobile system that uses multiple short narrowband bursts in different frequency channels for the transmission of one packet. Joint blind channel and CFO estimation over multiple freque...
Out-of-band radiation and CFO immunity of potential 5G multicarrier modulation schemes
Üçüncü, Ali Bulut; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2015)
In this study, generalized frequency division multiplexing (GFDM) and windowed cyclic prefix circular offset quadrature amplitude modulation (WCP-COQAM), which are candidate physical layer modulation schemes for the 5G systems, are compared to orthogonal frequency division multiplexing (OFDM) in terms of out-of-band (OOB) radiation levels and carrier frequency offset (CFO) immunity. GFDM and WCP- COQAM are shown to be superior to OFDM with respect to OOB emissions in some studies in literature. However, we c...
