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:
- fixed sample rate (48kSPS),
- fewer FIR filters.
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.
Some examples of software can be found at the following links:
- DiscoRedTRX (old version),
- Download SD card image zip file (more details about the SD card image can be found at this link).
- Copy the content of the SD card image zip file to an SD card.
- Optionally, to start the application automatically at boot time, copy its
apps/sdr_transceiver_embto the topmost directory on the SD card.
- Insert the SD card in Red Pitaya and connect the power.
