Digital signal with multiple reference blocks for channel estimation, channel estimation methods and corresponding receivers

摘要: A digital signal is organized in consecutive data trains each comprising a predetermined number of successive symbols, said at least two distinct reference blocks for the estimation channel, distributed among useful symbols representing source to be transmitted, being formed by one symbol known receiver and/or identifiable receiver. The present may explicit that are fixed and priori implicit produced links generated between an encoding operation. Also disclosed channel methods implementing estimation-maximization algorithm using combination basic functions, with bandwidth greater than or equal Doppler power spectrum signal.
