QPP interleaver/de-interleaver for turbo codes
摘要:
A quadratic permutation polynomial (QPP) interleaver is described for turbo coding and decoding. The QPP interleaver has the form: Π(n)=f1n−fnn2 mod K, where the QPP coefficients f1 and f2 are designed to provide good error performance for a given block length K.
