Timing errors in distributed space-time communications
نویسندگان
چکیده
In this paper we study the effects of timing errors on distributed space-time codes for collaborative communications. We assume a half duplex, decode and forward scheme, where two relaying nodes are not perfectly synchronized in forwarding. We analyze 1) the impact of this asynchronism on the performance of an Alamouti and a Golden code scheme with different types of detectors, and 2) the sensitivity of above schemes to timing errors with optimum detectors, when perfect knowledge of timing errors is assumed. 1

Surface Flow Routing using Kinematic Wave and Time – Area Methods for Upstream Watershed of the Bustan Dam in Golestan Province, Iran
This study aims to evaluate two methods of surface water routing including kinematic wave and time-area in upstream of the Bustan dam. To this end, first considering the features and application prerequisites of both methods and describing the hydraulic and hydrologic conditions within the Tamer watershed, algorithms and scripts of kinematic wave and time-area methods were developed. Then the s...

Ultra-wideband (UWB) radio is a promising technology for low-cost, high-rate communications at short ranges. However, high bandwidth and low power of the UWB signals impose some difficult challenges in signal processing and implementation of the receiver. Acquisition of the signal timing is the first task to be performed in a coherent receiver. The high bandwidth of UWB signals demand for fine ...
متن کاملSymbolic System Time in Network Testing
We propose an extension of symbolic execution of distributed systems to test software parts related to timing. Currently, the execution model is limited to symbolic input for individual nodes, not capturing the important class of timing errors resulting from varying network conditions. In this paper, we introduce symbolic system time in order to systematically find timing-related bugs in distri...
متن کاملLow-complexity symbol timing error detection for quasi-orthogonal space??time block codes
The author presents the design and analysis of low-complexity symbol timing error detectors (TEDs) for timing synchronisation in quasi-orthogonal space–time block code (QOSTBC) receivers. The estimators operate on data symbols and approximate decision variables, producing timing error measurements which are shown to be robust to channel fading. In evaluating the detector S-curve for the general...
متن کاملDistributed Space Time Codes with Low Decoding Complexity for Asynchronous Relay Networks
Recently Li and Xia have proposed a transmission scheme for wireless relay networks based on the Alamouti space time code and orthogonal frequency division multiplexing to combat the effect of timing errors at the relay nodes. This transmission scheme is amazingly simple and achieves a diversity order of two for any number of relays. Motivated by its simplicity, this scheme is extended to a mor...
