Channel estimation is a critical process at the receiver during the coherent detection of the transmitted STBC symbols and indices of the transmit antennas. In this paper, a spline interpolation and pilot symbols based channel estimation has been proposed for the space-time block coded spatial modulation (STBC-SM) systems to track the channel variations in the presence of Rician fading channels. The estimation of channel at pilot durations is done by least squares (LS) method and then the spline based channel interpolation is performed. It has been shown via computer simulations that the proposed spline based channel estimation channel estimation outperforms the piecewise linear interpolation (PLI) and the nearest neighbor interpolation (NNI) based channel estimations. © 2015 IEEE.trinfo:eu-repo/semantics/closedAccessMIMOPilot Symbol Assisted Channel EstimationSpatial ModulationSTBCTime Varying Rician Fading ChannelsAntennasFading channelsInterpolationLeast squares approximationsMIMO systemsModulationPiecewise linear techniquesSpace time codesSpace-time block coding (STBC)Least squares methodsNearest neighbor interpolationPiecewise linear interpolationsPilot symbol assistedRician fading channelSpace-time block codedSpatial modulationsSTBCChannel estimationConference Object18819110.1109/SIU.2015.71304452-s2.0-84939140291N/AN/A
