DSP's for Baseband Processing
Two Texas Instruments DSP's were evaluated for use in AUSDR-1, the TMDS320C5416, and the
TMDSC6711 DSK boards. The principle difference is that the '6711 is a floating-point machine, whereas
the '5416 has a fixed-point processor.

Code Development
DSP code was written using Code Composer Studio. The author wrote the majority of the code
that was used to perform the baseband processing for AUSDR-1.

Results from AUSDR-1
The experimental setup and results for AUSDR-1 is shown below in Fig'. B.2 through B.6.
The RF front end was successfully built and tested. Figures B.2 and B.3 are diagrams of the RF Receiver
front-end and RF transmitter front-end circuit respectively.
