virtual |
Divide the input signal with the current channel state.
Does the following (and nothing else):
- Divide every OFDM symbol with the current channel state
- If a pilot symbol is found, re-set the channel state by dividing the received symbol with the known pilot symbol
Implements gr::digital::ofdm_equalizer_base.
