Notes/Equations
- This model is used to implement channel coding.
Each firing, one token of block size and block number is consumed at BlkSize and BlkNum pins. DataIn consumes block size times block number tokens. This bit stream is then segmented as code blocks. Each code block is channel coded; the coded blocks are concatenated as specified in section 4.2.3.3 of [1]. - The coded data is output at DataOut; SizeOut indicates the size of coded data.
- The CHCodingType parameter determines the type of channel coding. This parameter, in conjunction with CRC and DynTFSet, consists of the format characteristics of the transport channel being processed.
