Abstract :
The problem of blind identifiability of a digital communication channel using second-order statistics of the received signal is addressed. A time series representation of the fractionally sampled digital signal is used to obtain a novel, necessary and sufficient condition for blind channel identification from the correlation and the conjugate correlation functions of the corresponding vector stationary process
