Abstract
The present invention envisions the use of a coherent signal to make up for lost or delayed samples to a modem. The modem contains a coherent phase buffer containing samples of at least a cycle of a coherent signal corresponding to an outgoing signal. When, for any reason, the samples for the outgoing signal are lost or delayed, the modem adaptively patches the outgoing signal with samples from the coherent phase buffer. The modem tracks the outgoing signal, and synchronizes a pointer into the coherent phase buffer outgoing signal. Thus, when the outgoing signal samples are delayed or lost, the modem may replace the invalid samples from the samples of the outgoing data signal with a patch of an appropriate sample or samples from the coherent phase buffer. As such, disruptions of the modem session associated with an incoherent signal during modem communications are avoided.
