SIGNAL LOSS COMPENSATION METHOD

A signal loss compensation method, for compensating an input signal comprising (K+Y) lost signal units and normal signal units. The signal loss compensation method comprises: compensating 1st to (K−1)th lost signal units by a first signal loss concealment algorithm to generate a first compensation signal and accordingly generating a first synthetic signal; compensating (K+X+1)th to (K+Y) th lost signal units by a second signal loss concealment algorithm to generate a second compensation signal and accordingly generating a second synthetic signal; compensating K th to (K+X)th lost signal units by the first signal loss concealment algorithm or the second signal loss concealment algorithm to generate a third synthetic signal; generating an output signal according to the first synthetic signal, the second synthetic signal, the third synthetic signal and the normal signal units. K and Y are positive integers, X is a natural number, and Y is larger than X.
