Abstract: |
In order to get a high throughput, QPP(Quadratic Permutation Polynomial) inner
interleaver is adopted fo
r Turbo parallel decoding.Through theoretical analysis, a new implementation me
thod
and architecture is proposed. Compared with the existing method, the proposed me
thod can reduce the complexity and resource consumption and is easily calculated
, and
simulation result shows that this method is correct. |
