#include <gr_ofdm_insert_preamble.h>
List of all members.
Detailed Description
insert "pre-modulated" preamble symbols before each payload.
input 1: stream of vectors of gr_complex [fft_length]
These are the modulated symbols of the payload.
input 2: stream of char. The LSB indicates whether the corresponding
symbol on input 1 is the first symbol of the payload or not.
It's a 1 if the corresponding symbol is the first symbol,
otherwise 0.
N.B., this implies that there must be at least 1 symbol in the payload.
output 1: stream of vectors of gr_complex [fft_length]
These include the preamble symbols and the payload symbols.
output 2: stream of char. The LSB indicates whether the corresponding
symbol on input 1 is the first symbol of a packet (i.e., the
first symbol of the preamble.) It's a 1 if the corresponding
symbol is the first symbol, otherwise 0.
- Parameters:
-
| fft_length | length of each symbol in samples. |
| preamble | vector of symbols that represent the pre-modulated preamble. |

Member Function Documentation
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.
