gr_ofdm_frame_sink2 Class Reference

Takes an OFDM symbol in, demaps it into bits of 0's and 1's, packs them into packets, and sends to to a message queue sink.NOTE: The mod input parameter simply chooses a pre-defined demapper/slicer. Eventually, we want to be able to pass in a reference to an object to do the demapping and slicing for a given modulation type. More...

Detailed Description

Takes an OFDM symbol in, demaps it into bits of 0's and 1's, packs them into packets, and sends to to a message queue sink.

NOTE: The mod input parameter simply chooses a pre-defined demapper/slicer. Eventually, we want to be able to pass in a reference to an object to do the demapping and slicing for a given modulation type.
