A Novel Parallel Turbo Coding Technique Based on Frame Split and Trellis Terminating
In this paper, a new parallel Turbo encoding and decoding technique is introduced. In this technique, a long information data frame is first divided into sub-blocks which are then encoded with trellis terminating and decoded by parallel multiple SISO modules. It is shown that, at a slight increase in hardware complexity and a slight loss in the transmission efficiency due to the extra terminating bits appended, the proposed scheme can effectively reduce the decoding delay, and at the same time achieve noticeably better error performance compared with the regular schemes, especially in high code rate situation.
