The present invention relates to the field of wireless communications. Provided in an embodiment of the present invention are a training sequence generation device, apparatus and method, the device comprising a sequence length determination module, a first sequence generation module, a second sequence generation module, a first power ratio calculation module, a threshold detection module and a first sequence determination module. The present invention determines the length of a sequence according to the total number of system subcarriers, generates a Golay sequence according to the length of the sequence, generates a training sequence based on the Golay sequence and detects whether the PAPR of the training sequence is less than a preset threshold; if so, then determining that the training sequence is a long training sequence of the system. Because the Golay sequence has a low PAPR, the long training sequence of the system generated based on the Golay sequence can acquire the low PAPR of the Golay sequence, and improve the estimated performance of a channel. |
