Abstract
A digital transmission system wherein only certain of the samples in a series of signal samples are transmitted by the transmitter to a receiver over a channel. In addition, various characteristic parameters of the series of signal samples are determined in the transmitter and transmitted to the receiver. The characteristic parameters are used at the receiver to reconstruct the missing single samples by assigning to them values such that the resulting reconstructed series of signal samples approximates the characteristic parameters as closely possible. If the series has a periodicity having a period longer than the time duration of the series of signal samples, reconstruction of the series may have a considerable interpolation error. By determining such period in the transmitter and transmitting it over the channel to the receiver, where the same periodicity is introduced into the reconstructed series of signal samples, the interpolation error is considerably reduced.
