Sammanfattning

A speech data packet loss concealment algorithm based on pitch period repetition is presented and a novel low complexity method to refine a pitch period estimate is introduced. Objective performance measurements show that this pitch refinement improves the quality of packet loss concealment. Hardware-software codesign techniques have been investigated to implement the algorithm. Using a coprocessor approach, a processing delay of 0.9 ms and a overall speedup of 3.3 was achieved
