Cyclostationarity based blind block timing estimation for alamouti coded MIMO signals. IEEE Communications Letters, 21(6), 1341-1344. doi:10.1109/LCOMM.2017.26774201089-77981558-2558https://hdl.handle.net/11729/1489http://dx.doi.org/10.1109/LCOMM.2017.2677420Blind parameter estimation algorithms provide a powerful tool for application scenarios where the use of training or pilot sequences is not desirable, e.g., in order to improve the bandwidth efficiency of the transmission, or in noncooperative scenarios where such sequences are not available to the receiver. This letter proposes a blind block timing estimation algorithm for Alamouti space-time block coded signals exploiting the second order joint cyclostationary characteristics of the received signal vector, which is induced by the space time block coding operation performed by the transmitter. The proposed algorithm outperforms the existing algorithms by a wide margin.eninfo:eu-repo/semantics/closedAccessAlamouti space-time block codeMIMOBlind parameter estimationTiming synchronizationMIMO communicationSpace-time block codesAntenna arraysModulationRadio receiversTransmitting antennasCognitive radioEstimation theoryInterference (signal)Parameter estimationPhase shift keyingRadio transmittersSignal detectionVectorsOFDM modulationCellular radioWireless LANChannel allocationChannel estimationSignal processingTiming jitterBlind source separationCorrelation methodsHigher order statisticsIndependent component analysisArticle21613411344Q2Q2WOS:0004034313000312-s2.0-8502092101710.1109/LCOMM.2017.2677420Q1
