[hpsdr] Introducing Angelia

[f6bki at orange.fr]

ABhi, What is going to be the difference between the multiple Mercury  platform and Angelina as far diversity and beam forming is concerned ? are the software developed for one can be used for the other ? is the issue of phase at start up you have describe on Mercury  solved ?
Thank you

Hi All,

Joe, K5SO and myself had been working on beam forming and DF applications using the modular multiple Mercury platform, initial results were extremely promising, however, we had to overcome an issue of each Mercury receiver starting up at a random phase on power up, 

Angelia is an outcome of this work and resolves the issue, the receive performance is identical to Hermes and Mercury, 

Angelia is a state-of-the-art soft core uP 4th generation DDC/DUC, a soft core processor such as the NIOS-II or similar can be build right into the FPGA for all the heavy lifting, there is enough room in the FPGA for all sorts of possibilities, this is better than using a physical Cortex A8 or similar processor as you may upgrade your uP in the code, this puts OpenHPSDR back in the technology lead where it belongs! Thanks to Phil, Kevin, Kjell, Alex, Doug, Bill, Hermann and others without whose work this would not have been possible,

For folks who are buying Hermes, Angelia would be much more expensive and you do not gain in performance unless you are going to use diversity reception or beam forming,

OpenHPSDR is again the first to show a working prototype, you can have a look at the  prototype Here: http://www.youtube.com/watch?v=_r5MO1Fz5OU&feature=youtu.be

I'll try and make a better video as soon as I get some free cycles :),

73s,
ABhi
