Methods of Joint Operation for Extremely High Doppler Shift Estimation and Control Channel False Positive Rate Reduction and for Side-Link V2x Communications in Extreme High Speed Scenarios

Abstract:

A communication device includes one or more processors, configured to receive data representing each of at least a first waveform and a second waveform from a common control channel and data representing a third waveform from a data channel associated with the control channel; determine from the received data, channel state information for each of the first waveform and the second waveform; determine a Doppler shift between the channel state information for the first waveform and the channel state information for the second waveform; compare the determined Doppler shift to a predetermined Doppler shift threshold; and if the determined Doppler shift is less than the predetermined Doppler shift threshold, adjust the third received waveform by the determined Doppler shift and decode the adjusted third received waveform.
