Detailed Description

Map a stream of symbol indexes (unpacked bytes or shorts) to stream of float or complex onstellation 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_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 gr_chunks_to_symbols_if::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_block.

int gr_chunks_to_symbols_if::work (  int  noutput_items, gr_vector_const_void_star &  input_items, gr_vector_void_star &  output_items )  [virtual]

just like gr_block::general_work, only this arranges to call consume_each for you The user must override work to define the signal processing code Implements gr_sync_block.
