Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for turbo coding and decoding that appropriately matches a CTB to available FEC block sizes.
SOLUTION: During operation, a concatenated transport block (CTB) of length X is received and a forward error correction (FEC) block size K
I is determined from a group of available non-contiguous FEC block sizes between K
min and K
max , wherein K
min ≤K
I max , and K
I-1 and K
I are additionally based on X. The concatenated transport block of length X is segmented into C segments each of size substantially equal to K
I . An FEC codeword for each of the C segments is determined using FEC block size K
I , and the C FEC codewords are transmitted over a channel.

Abstract: During operation of a transmitter a circular buffer is created where only column tops of the circular buffer are defined as a starting position for a redundancy version. Where the circular buffer is in sequence format, all po ssible redundancy versions are positioned as a function of the column index of the starting position of the first redundancy version.

Abstract: A structured parity-check matrix H is proposed, wherein H is an expansion of a base matrix H b and wherein H b comprises a section H b1 and a section H b2 , and wherein H b2 comprises a first part comprising a column h b having an odd weight greater than 2, and a second part comprising matrix elements for row i, column j equal to 1 for i = j , 1 for i = j+1, and 0 elsewhere. The expansion of the base matrix H b uses identical submatrices for 1s in each column of the second part H ' b2 , and the expansion uses paired submatrices for an even number of 1s in h b .

Abstract: A base model matrix is defined for the largest code length of each code rate. The set of shifts {p(i,j in the base model matrix are used to determine the shift sizes for all other code lengths of the same code rate. Shift sizes {p(f,i,j for a code size corresponding to expansion factor z f are derived from {p(i,j by scaling p(i,j) proportionally, and a model matrix defined by {p(f,i,j is used to determine the parity-check bits for the f-th code.
