Embedded SDR transceiver


This version of the Red Pitaya SDR transceiver may be useful for building a small standalone SDR transceiver with all the SDR algorithms running on the on-board CPU of the Red Pitaya board.


The structure of this version is very similar to the SDR transceiver described at this link. The two main differences are:

The basic blocks of the digital down-converters (DDC) and of the digital up-converters (DUC) are shown on the following diagram:

The projects/sdr_transceiver_emb directory contains four Tcl files: block_design.tcl, rx.tcl, sp.tcl, tx.tcl. The code in these files instantiates, configures and interconnects all the needed IP cores.
