Detailed Description
Evaluate metrics for use by the Viterbi algorithm.
Member Function Documentation
| int trellis_metrics_s::D | ( | ) | const [inline] |
| void trellis_metrics_s::forecast | ( | int | noutput_items, |
| gr_vector_int & | ninput_items_required | ||
| ) | [virtual] |
Estimate input requirements given output request.
- Parameters:
-
noutput_items number of output items to produce ninput_items_required number of input items required on each input stream
Given a request to product noutput_items, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.
Reimplemented from gr_block.
| int trellis_metrics_s::general_work | ( | int | noutput_items, |
| gr_vector_int & | ninput_items, | ||
| gr_vector_const_void_star & | input_items, | ||
| gr_vector_void_star & | output_items | ||
| ) | [virtual] |
compute output items from input items
- Parameters:
-
noutput_items number of output items to write on each output stream ninput_items number of input items available on each input stream input_items vector of pointers to the input items, one entry per input stream output_items vector of pointers to the output items, one entry per output stream
- Returns:
- number of items actually written to each output stream, or -1 on EOF. It is OK to return a value less than noutput_items. -1 <= return value <= noutput_items
general_work must call consume or consume_each to indicate how many items were consumed on each input stream.
Implements gr_block.
