BCH Coding

A Python wrapper around the AFF3CT [1] project, transferring the Bose–Chaudhuri–Hocquenghem [2] code implementations to the Hermes forward error correction pipeline structure.

class BCHCoding(self: hermespy.fec.aff3ct.bch.BCHCoding, arg0: int, arg1: int, arg2: int)

Bases: pybind11_object

Parameters:

  • data_block_size (int) – Number of data bits per block to be encoded.

  • code_block_size (int) – Number of code bits per encoded block.

  • power (int) – Number of corretable bit errors.

decode(self: hermespy.fec.aff3ct.bch.BCHCoding, arg0: numpy.ndarray[numpy.int32]) → numpy.ndarray[numpy.int32]

Decode a block of code bits to data bits.

Parameters:

code (numpy.ndarray) – The code bit block to be decoded.

Returns:

The data bit block after decoding.

encode(self: hermespy.fec.aff3ct.bch.BCHCoding, arg0: numpy.ndarray[numpy.int32]) → numpy.ndarray[numpy.int32]

Encode a block of data bits to code bits.

Parameters:

data (numpy.ndarray) – The data bit block to be encoded.

Returns:

The code bit block after encoding.

property bit_block_size

Number of bits within a data block to be encoded.

property code_block_size

Number of bits within a code block to be decoded.

property correction_power

Number of corretable bit errors.
