Abstract
Various examples relate to a concept for generating and using a preamble for transmissions in a point-to-multipoint network, such as a Passive Optical Network (PON). A preamble generation apparatus for generating a preamble for a communication over an optical network comprises circuitry that is configured to generate a first subsection of the preamble, the first subsection of the preamble comprising a repetitive signal pattern. The preamble generation apparatus is configured to generate a second subsection of the preamble subsequent to the first subsection, the second subsection comprising a pseudorandom signal sequence.
Claims21
A preamble generation apparatus for generating a preamble for a communication from an optical network unit to an optical line terminal over an optical network, the preamble generation apparatus comprising interface circuitry and processing circuitry configured to:
- receive a preamble configuration message from the optical line terminal, wherein the preamble configuration message comprises at least one of a generator polynomial and an initialization seed;
- generate a first subsection of the preamble, the first subsection of the preamble comprising a repetitive signal pattern;
- generate a second subsection of the preamble subsequent to the first subsection, the second subsection comprising a predetermined signal sequence, wherein the predetermined signal sequence is generated based on the preamble configuration message.
A terminal unit comprising a transmitter and a receiver for an optical network,
- the transmitter configured to:
- transmit a preamble configuration message to a network unit of the optical network, the preamble configuration message comprising information on an algorithm to be used to generate a predetermined signal sequence of a second subsection of the preamble, and
- the receiver comprising configured to:
- receive a data burst comprising the preamble, the preamble comprising a first subsection comprising a repetitive signal pattern, and the second subsection of the preamble subsequent to the first subsection, the second subsection comprising the predetermined signal sequence;
- and
- determine information for an error correction code or information for a non-linear equalizer using the predetermined signal sequence of the preamble.
