Block Turbo Codes
Kluwer Academic Publishers eBooks · 2006
This chapter presented the idea of block turbo codes, including the way they are encoded and decoded. Two main decoding approaches were presented, namely, the algebraic decoding and Trellis-based decoding. The details of the algebraic decoding, i.e., modified Chase-II algorithm were presented, along with an example. Some simulation results from the literatures of BTCs using algebraic-based iterative decoding were also presented. It was shown that BCH-BTCs perform well at high code rates, i.e., R/C ≈ 1.
