Patent ID: 8356232

Claim:
A method of operating a transmitter, the method comprising the steps of: receiving a concatenated transport block of length X; determining an available FEC block size K I from a group of non-contiguous FEC block sizes, wherein the available non-contiguous FEC block sizes are between K min and K max , and wherein K min <=K I <K max , and wherein K I is additionally based on X; segmenting the concatenated transport block of length X into C segments of sizes substantially equal to K I ; determining an FEC codeword for each of the C segments using FEC block size K I ; transmitting the C FEC codewords over the channel; inserting groups of consecutive filler bits into a segment to form an FEC input block wherein the group length is a multiple of 7; FEC encoding the FEC input block; and discarding bits related to the filler bits.
