The invention provides a training method for a non-Nyquist transmission system and a training data transmission apparatus for a non-Nyquist transmission system by which initialization processing of a reception section can be performed with certainty even where a non-Nyquist transmission system is employed. Prior to transmission of data in accordance with a non-Nyquist transmission system, training data having a first repeat signal portion formed from a group of signals including components of a lower rate than a Nyquist interval, a first multi-value random signal portion formed from multi-value random signals, a second repeat signal portion formed from a group of signals including components of a lower rate than the Nyquist interval, a third repeat signal portion formed from a group of signals which include components lower in rate than the Nyquist interval and wherein a first signal point is different by 180 degrees in phase from a first signal which forms the second repeat signal portion, and a second multi-value random signal portion formed from multi-value random signals, are transmitted from a transmission section. The training data are received by a reception section, and initialization processing of the reception section is performed using the received training data.
