Detailed Description

Map a stream of symbol indexes (unpacked bytes or shorts) to stream of float or complex constellation points in D dimensions (D = 1 by default)

input: stream of int; output: stream of float.

out[n D + k] = symbol_table[in[n] D + k], k=0,1,...,D-1

The combination of gr::blocks::packed_to_unpacked_XX followed by digital_chunks_to_symbols_XY handles the general case of mapping from a stream of bytes or shorts into arbitrary float or complex symbols.
