The ntOFDM_HS_BBP IP implements the physical layer transmission and reception processing engines of a custom subset of the 802.16-2012 standard. The ntOFDM_HS_BBP IP core main functional blocks are the Transmitter, the Receiver, the Register File and High Level Controller and the Analog Front End interface. The User programs the Register file in order to define the systems functionality, configure control parameters, and define the desired modes of operation. The Analog Front End interface module connects the ntOFDM_HS_BBP produced sample rate to the any AFE board with all the appropriate rate conversions.
