"Implementing Forward Error Correction with Vandermonde Matrices" is a software solution that uses a specialized mathematical technique to improve data transmission reliability. With this tool, you can reduce the impact of communication errors and corruptions, ensuring smooth delivery of your data.
Allowed values for data_blocks and encoded_blocks must obey a specific equation. The library provides multiple methods to encode and decode blocks.
One method, encode, creates a single encoded block of index block_index which must be between 0 and encoded_blocks-1 (inclusive). The blocks from 0 to data_blocks-1 are simply copies of the original data blocks.
The set_decode_blocks method prepares to decode data_blocks of blocks. An array of indices must be supplied as the second arrayref. Both arrays must have exactly data_blocks entries. This method also reorders the blocks and index array in place (if necessary) to reflect the order the blocks will have in the decoded result.
The shuffle method is the same as set_decode_blocks, with the exception that the blocks are not actually set for decoding. This method is not normally used, but if you want to move blocks around after reordering and before decoding, then calling shuffle followed by set_decode_blocks incurs lower overhead than calling set_decode_blocks twice.
The decode method decodes the blocks set by a prior call to set_decode_blocks. It destroys the block array as set up by set_decode_blocks.
The copy method is a utility function that simply copies one block (specified like in set_encode_blocks) into another. This method destroys the blocks set by set_*_blocks.
Overall, Algorithm::FEC provides a useful interface to the fec library for encoding and decoding blocks.
