Patent ID: 8140946

Claim:
A method comprising: encoding information bits to output a coded signal using turbo code encoding with a low code rate, wherein the encoding utilizes constituent encoding having a transfer function: G ⁡ ( D ) = [ n 0 ⁡ ( D ) d ⁡ ( D ) , n 1 ⁡ ( D ) d ⁡ ( D ) , … ⁢ ⁢ n 4 ⁡ ( D ) d ⁡ ( D ) ] where, d ( D )=1 +D+D 3 n 0 ( D )=1 +D 2 +D 3 n 1 ( D )=1 +D+D 2 +D 3 n 2 ( D )=1 +D 3 n 3 ( D )=1 +D+D 2 n 4 ( D )=1 +D.
