AB  - This paper proposes a hybrid Packet Loss Concealment (PLC) algorithm for memoryless encoders such as PCM. The concealment algorithm integrates two modes, one in the time domain and the other in the frequency domain. Mode selection is performed using the previous, correctly received samples prior to an erased packet. This hybrid approach provides a packet loss concealment mechanism which can adapt to the signal characteristics and is not restricted to pure speech signals. Subjective evaluations have demonstrated that the proposed algorithm performs significantly better than single mode concealment algorithm.
