F. Mazzenga, BLIND IDENTIFIABILITY OF A CHANNEL TRANSFER-FUNCTION FROM THE CORRELATION AND CONJUGATE CORRELATION-FUNCTIONS OF A FRACTIONALLY SAMPLED SIGNAL, Electronics Letters, 33(23), 1997, pp. 1917-1918
The problem of blind identifiability of a digital communication channe
l 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 bli
nd channel identification from the correlation and the conjugate corre
lation functions of the corresponding vector stationary process.
