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 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.

Member Function Documentation

bool digital_chunks_to_symbols_ic::check_topology	(	int	ninputs,
		int	noutputs
	)		[inline, virtual]

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.
