Zero state doped turbo equalizer

Although iterative equalizers perform well at low signal to noise ratios, high latency is a major disadvantage for their use in practical communication systems. In this article we propose zero state doped turbo equalizers (ZSDTEs) which can be processed in parallel and have significantly reduced processing delays. The proposed technique shows better performance when compared to the sliding window method.

Fast decodable turbo codes
Gazi, Orhan; Yılmaz, Ali Özgür (Institute of Electrical and Electronics Engineers (IEEE), 2007-02-01)
Decoding delay is an important consideration for the use of turbo codes in practical applications. We propose a new structure for turbo codes which is very suitable for parallel decoding. It is shown by union bound analysis and simulation results that the proposed system performance is comparable to that of the classical turbo codes.
Cooperative diversity in carrier frequency offset
Yılmaz, Ali Özgür (Institute of Electrical and Electronics Engineers (IEEE), 2007-04-01)
Cooperative diversity can enjoy the same benefits of MIMO systems when there is no possibility of carrying multiple antennas on a communication terminal. The main distinction between MIMO and cooperative diversity systems is the inherent asynchronism in the latter. We propose a model to study the effects of carrier frequency offset along with symbol asynchronism. Based on the proposed model, a Viterbi equalizer is utilized as a solution for demodulation. Through simulations, it is observed that such a solut...
Sector Scanning Attempts for Non-Isolation in Directional 60 GHz Networks
Olcer, Gencay Mutlu; Genc, Zulkuf; Onur, Ertan (Institute of Electrical and Electronics Engineers (IEEE), 2010-09-01)
Large path losses of millimeter waves restrain the acceptance of 60 GHz technology in future networks. Directional antennas can be exploited in 60 GHz networks to mitigate the detrimental impact of fading. Employing fully directional antennas complicates the neighbor discovery process where each sector must be probed individually to discover neighbors located in that sector. In random scanning strategy, nodes select to-be-scanned sector randomly. In this letter, we analyze the minimum number of random secto...
Delay aware reliable transport in wireless sensor networks
Gungor, Vehbi C.; Akan, Oezguer B. (Wiley, 2007-10-01)
Wireless sensor networks (WSN) are event-based systems that rely on the collective effort of several sensor nodes. Reliable event detection at the sink is based on collective information provided by the sensor nodes and not on any individual sensor data. Hence, conventional end-to-end reliability definitions and solutions are inapplicable in the WSN regime and would only lead to a waste of scarce sensor resources. Moreover, the reliability objective of WSN must be achieved within a certain real-time delay b...
Triple stub circuit topology as simultaneous insertion phase, amplitude and impedance control circuit for phased array applications
Unlu, M.; Demir, Şimşek; Akın, Tayfun (Institution of Engineering and Technology (IET), 2012-10-23)
This study shows that the well-known triple stub circuit topology can also be used for controlling the insertion phase and amplitude of a given signal simultaneously, as well as preserving its impedance transformation ability. The triple stub circuit topology, which is nothing but an extension of the conventional double stub loaded-line phase shifter, results in one more degree of freedom to its solution when it is solved for its insertion phase. This additional degree of freedom not only brings the impedan...
