Improved encoding structure and decoding algorithms for spinal codes
文献摘要：
To improve the error correction performance, an inno-vative encoding structure with tail-biting for spinal codes is designed. Furthermore, an adaptive forward stack decoding (A-FSD) algorithm with lower complexity for spinal codes is pro-posed. In the A-FSD algorithm, a flexible threshold parameter is set by a variable channel state to narrow the scale of nodes accessed. On this basis, a new decoding method of AFSD with early termination (AFSD-ET) is further proposed. The AFSD-ET decoder not only has the ability of dynamically modifying the number of stored nodes, but also adopts the early termination criterion to curtail complexity. The complexity and related parameters are verified through a series of simulations. The sim-ulation results show that the proposed spinal codes with tail-bit-ing and the AFSD-ET decoding algorithms can reduce the comple-xity and improve the decoding rate without sacrificing correct decoding performance.
