POLAR Decoder SC Definition

Standard successive cancellation (SC) decoder for POLAR codes

It expects float input with bits mapped 1 --> 1, 0 --> -1 Or: f = 2.0 * bit - 1.0

Parameters

 * Parallelism
 * For parallel execution of multiple instances of the block (more info is needed on this)


 * Dimension 1
 * For parallelism


 * Dimension 2
 * For parallelism


 * Block size (N)
 * Codeword size. MUST be a power of 2.


 * #Info Bits (K)
 * Represents the number of information bits in a block. Also called frame_size. <= block_size


 * Frozen Bit Positions
 * Integer vector which defines the position of all frozen bits in a block. Its size MUST be equal to block_size - num_info_bits. Also it must be sorted and every position must only occur once.


 * Frozen Bit Values
 * Holds an unpacked byte for every frozen bit position. It defines if a frozen bit is fixed to '0' or '1'. Defaults to all ZERO.

Example Flowgraph
Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
