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 short; output: stream of gr_complex
out[n D + k] = symbol_table[in[n] D + k], k=0,1,...,D-1
The combination of gr_packed_to_unpacked_XX followed by gr_chunks_to_symbols_XY handles the general case of mapping from a stream of bytes or shorts into arbitrary float or complex symbols.

Confirm that ninputs and noutputs is an acceptable combination.
- Parameters
-
ninputs number of input streams connected noutputs number of output streams connected
- Returns
- true if this is a valid configuration for this block.
This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures.
Reimplemented from gr_basic_block.
