Abstract:
1. A method for feeding a stream of digital transmission data into a transmission medium, comprising: accepting a digital payload data; inserting the digital payload data into the stream of digital transmission data at a predetermined first position; generating a supplementary digital data using the digital payload data by the feed circuit so that at least one frequency portion in a frequency spectrum of the stream of digital transmission data is minimized; inserting the supplementary digital data into the stream of digital transmission data at a predetermined second position; and feeding the stream of digital transmission data into the transmission medium, wherein the stream of digital transmission data comprises a plurality of groups of transmission data, wherein each group of transmission data comprises two intrinsically coherent blocks of transmission data, wherein the two blocks have block lengths, wherein one of the blocks comprises exclusively the payload data or exclusively the supplementary data, wherein the block lengths are one bit or greater than one bit, wherein the block lengths are identical or different, wherein the payload data is fed into the transmission medium at a payload data readout clock rate and the supplementary data is fed into the transmission medium at a supplementary data readout clock rate, wherein the payload data readout clock rate and the supplementary data readout clock rate are identical or different, and wherein the block lengths and the payload data readout clock readout clock rate and the supplementary data readout clock rate are determined based on a relationship wherein lN is a block length of the block comprising the payload data, TN is a time for feeding a single item of the payload data into the transmission medium, lE is a block length of the block comprising the supplementary data, TE is a time for feeding a single item of the supplementary data into the transmission medium, and T is a time for accepting a single item of the payload data into the feed circuit.
