Claim 7:
8. The method according to claim 7, wherein the performing secondary channel closed-loop pitch period search based on the estimated pitch period value of the first primary channel signal, to obtain an estimated pitch period value of the first secondary channel signal comprises:
performing closed-loop pitch period search by using integer precision and fractional precision and by using the closed-loop pitch period reference value of the first secondary channel signal as a start point of the first secondary channel signal closed-loop pitch period search, to obtain the estimated pitch period value of the first secondary channel signal, wherein the closed-loop pitch period reference value of the first secondary channel signal is determined based on the estimated pitch period value of the first primary channel signal and the quantity of subframes of the first secondary channel signal.
