22 * \brief Map a stream of unpacked symbol indexes to stream of
23 * float or complex constellation points in D dimensions (D = 1 by
24 * default) \ingroup converter_blk
25 *
26 * \details
27 * \li input: stream of IN_T
28 * \li output: stream of OUT_T
29 *
30 * \li out[n D + k] = symbol_table[in[n] D + k], k=0,1,...,D-1
31 *
32 * The combination of gr::blocks::packed_to_unpacked_XX followed
33 * by gr::digital::chunks_to_symbols_XY handles the general case
34 * of mapping from a stream of bytes or shorts into arbitrary
35 * float or complex symbols.
