Abstract: UST symbol-based turbo code has recently been proposed which can reduce the system complexity and calculation amount compared with bit-wise concatenation scheme. However, the corresponding ...

Abstract: The authors present a soft-input soft-output (SISO) turbo decoder based on the two-step soft-output Viterbi algorithm (SOVA). The turbo decoder has been implemented with the trace-back ...

FEC (forward-error-correction) techniques correct errors at the receiver end of digital communications systems. In contrast with error-detection and retransmission ...
