Map a stream of unpacked symbol indexes to stream of float or complex constellation points in D dimensions
out[n D + k] = symbol_table[in[n] D + k], k=0,1,...,D-1
The combination of Packed to Unpacked followed by this block handles the general case of mapping from a stream of bytes or shorts into arbitrary float or complex symbols.
Parameters
(R): Run-time adjustable
- Symbol table (R)
- list that maps chunks to symbols. That list should have a length of <number of symbols> x <dimension of the table>
- Dimension
- Dimension of the table.
- Num ports
- Number of input and output stream to process. Each stream is processed isolated from each other.
