ARP interleaver design tool for turbo codes: distance-driven layer-by-layer search using decoder-free mHD estimation. Supports arbitrary RSC encoders, puncturing patterns, and all LTE block sizes.

Design and simulation toolkit for Decomposed Parallel Concatenated Convolutional Codes (DPCCC): a novel turbo code structure with improved minimum Hamming distance. Includes decoder-free interleaver design, N-impulse design, and Monte Carlo BER/FER simulation.
