Inserts an erasure value inside the punctured input data stream. The erasure value is equivalent to inserting a null symbol in the position of the input data stream that was previously punctured using MT Puncture Data Stream.
The data stream with a rate to be increased by the process of depuncturing. This data stream is usually obtained from the output of a block or convolutional encoder.
A binary-valued matrix that determines which elements in the input data stream are omitted.
The symbol value to be inserted into the punctured data stream before decoding. The erasure value is equivalent to inserting a null symbol in the position of the input data stream that was previously punctured using MT Puncture Data Stream.
The value of the erasure symbol inserted depends on the decoding scheme employed following the depuncturing operation. Using a soft-decision Viterbi decoder with n soft bits used to quantize every BPSK modulated symbol, the erasure value must be (2 n soft -1)/2. On the other hand, if the decoder is an unquantized Viterbi decoder, which accepts real-valued BPSK data symbols lying in [-1, 1], the erasure value must be 0. The integer value 0 denotes a strong logic 0, and 2 n soft -1 denotes a strong logic 1.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: no error
A Boolean that determines whether this node uses the stored state information from a previous iteration while depuncturing the input data stream in the current iteration.
|TRUE||Clears all previous state information and reinitializes the buffers.|
|FALSE||Uses the stored state information from the previous iteration while depuncturing the input data stream in the current iteration. The buffered elements are added to the beginning of the input data stream during the next iteration, prior to the depuncturing operation.|
The data stream returned by this node, which consists of all elements in the input data stream in addition to those that were inserted during the depuncturing operation.
