BURST SYNCHRONIZATION ON UNKNOWN FREQUENCY $ELECTIVE ANTENNA ARRAY CHANNELS WITH CO-CHANNEL INTERFERENCE USING AN
David Astély, Andreas Jakobsson, Lee Swindlehurst · 2009
Abstract- In this work, burst oriented data transmission over unknown frequency selective channels is considered. The receiver is assumed to use multiple antennas and the problem of estimating the start position of a data packet in the presence of spatially correlated co-channel interference is addressed. Each burst is assumed to contain a known training sequence, and in the paper metrics for finding the position of this training sequence are studied. More specs-cally, we examine the advantages of taking the spatial corre-lation of the co-channel interference into account, as com-pared with treating it as spatially white. Simulations and experimental results for transmission of normal GSM bursts in interference limited scenarios are presented. I.
