TRANSMISSION SYSTEM FOR QUASI-PERIODIC SIGNALS

摘要

In a transmission system for a quasi-periodic signal, an encoder (12) transmits to a decoder (28) no more than a single period from a total number of periods of the quasi-periodic signal in encoded form. In this decoder (28) the lacking periods of the quasi-periodic signal are reconstructed by means of interpolation. For obtaining an enhanced quality of the reconstructed signal, a signal segment is transmitted that is representative of two successive periods of the quasi-periodic signal. This signal segment may contain two successive periods, but may also be a signal segment having the length of a single period and being determined by a weighted sum of two successive periods.
