Abstract： |
The invention belongs to filed of digital information transmission technique, it characterized in that, aiming at current multi-carrier and single carrier modulating system which is based on multi-mode training sequence, using multi-mode correlator to resolve problem of automatic identification. Local relative sequence in different modes of serires, parallel or mixing mode is weight and assembled to design new local multi-mode relative sequence, by identifying position difference; size of relative peak, property of secondary relative peak of adjacent relative peak, mode used can be judged. Aiming at DTMB system, the invention gives out a design method of concrete multi-mode correlator, simulation of computer expresses that the multi-mode correlator can identify system working mode precisely, and it possesses characters that length of local relative sequence is reasonable and hardware is easy to realize. |
