Abstract
In a system for transmitting information via a time-varying transmission channel, learning information is transmitted in addition to wanted information to enable the transmission channel to be estimated at the receiving end. The system estimates if it is necessary to transmit learning information given the current variations of the transmission channel and transmits learning information only if this is deemed necessary.
