“…In [10], [11], the two decoders operate in synchronous manner: when the first decoder is working on its decoding, it considers the instantaneously generated extrinsic values form the other one, bit by bit. A method is proposed in [12] to use twice the number of decoders: as two SISO decoders per a convolutional code. Each one of the twin decoders run in the opposite direction to deliver the LLRs faster to the other decoders.…”

Reducing the decoding latency of the turbo codes is important to real-time applications. Conventionally, the decoding of the turbo codes (TC) runs in serial fashion, which means only one of the constituent soft decoders runs at a time. Parallel decoding (PD) refers to running the soft decoders in parallel. Although it delivers the output faster (compared to the serial decoding (SD)), it affects the bit- and frame-error rates. This paper proposes a decoding procedure that combines both PD and SD. It bridges the two decoding modes to determine the best combination scheme to achieve the required level of performance at an acceptable decoding latency. Presented results show how this procedure can mitigate the performance degradation at a slight increase in the decoding latency.
