Abstract:
1. A method for transmitting an analog datastream from a datastream transmitter to a datastream receiver, the method comprising: inputting data to be transmitted into a data input device of a datastream transmitter; coding the data to be transmitted, thereby generating coded data; assembling the coded data into coded data blocks; transforming the coded data blocks into at least one discrete multitone symbol; extracting at least one initial filter value from the at least one discrete multitone symbol; forwarding the at least one initial filter value to a stored-value determining device; applying a frame alignment signal to the stored-value determining device; determining, as a function of the at least one initial filter value and the frame alignment signal, at least one stored value for a first filtering device; applying the at least one stored value to the first filtering device; applying the at least one discrete multitone symbol to the first filtering device to provide a filtered discrete multitone symbol; forwarding the filtered discrete multitone symbol to a second filtering device to which the at least one stored value determined in the stored-value determining device is applied, to provide a transient-compensated discrete multitone symbol; converting the transient-compensated discrete multitone symbol into an analog transmitter signal; and transmitting the analog transmitter signal via a transmission channel.
