pycodes

The pycodes package provides various extensions to Python for low density parity check (LDPC) codes, an extremely powerful class of error correcting codes. LDPC codes can be used for physical layer error correction in wireless, telephone, DSL, or cable modems; packet loss correction in multicast and distribution of bulk data over the Internet; and even data compression. Most of the LDPC routines are written in C and linked into Python.
