… Another object of the invention is to devise a training procedure and apparatus for modem
receivers which allow the optimum utilization of a training signal whose period is known to
the receiver, whose length, however, need not be known to the receiver. a further object of
the invention is a method of training signal detection in modem receivers that allows to obtain
rapidly a precise estimate of the carrier frequency offset of the received signal. … A further
