Abstract
Disclosed herein are various embodiments of coding systems and methods. In one method embodiment, among others, a coding method comprises receiving input parameters, and providing a packet comprising variable FEC code block sizes throughout the packet structure based on the input parameters.
Claims29
A coding method, comprising:
- receiving input parameters;
- and
- providing a packet comprising variable forward error-correction (FEC) code block sizes throughout the packet structure based on the input parameters.
A method of computing encoding parameters, the method comprising:
- determining a number of bits per orthogonal frequency division multiplexing (OFDM) epoch corresponding to a packet and packet size;
- determining a minimum transmission packet size and base code rate that can be supported in the determined packet size;
- performing an initial calculation of a number of code blocks to be used in the packet;
- determining a shortening mechanism and updating a number of base codewords to be used in the packet if needed;
- determining a number of largest size based codewords in a main body to be used in the packet;
- determining an optimum tail sequencing of codeword sizes to be used at the end of the packet;
- and
- outputting adapted codeword lengths and shortening and puncturing parameters corresponding to the packet.
