Member Function Documentation

void gr::digital::ofdm_chanest_vcvc_impl::forecast ( int  noutput_items,
gr_vector_int ninput_items_required 
)
virtual

Estimate input requirements given output request.

Parameters
noutput_itemsnumber of output items to produce
ninput_items_requirednumber 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 gr::digital::ofdm_chanest_vcvc_impl::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_itemsnumber of output items to write on each output stream
ninput_itemsnumber of input items available on each input stream
input_itemsvector of pointers to the input items, one entry per input stream
output_itemsvector 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.
