[Discuss-gnuradio] learning about SDR

2007-05-18 Thread Brett L. Trotter
I've been learning about software defined radio from the ground up and my maths are a bit shaky and I'm mainly a software guy, so concepts of signals and whatnot are rather foreign to me. So as I've been reading, I've taken lots of tangents to review what must seem like completely elementary concep

Justin - Thanks for the tip. I did figure out how to correct the issue on my native Ubuntu install: change the sound preferences to all be for "ALSA" ... no idea why this works, but it did. The VM install still doesn't work (even with your tip), but that's probably a VMware issue. - MLD

[Discuss-gnuradio] r/s encoding and padding on gmsk

2007-05-18 Thread Brett L. Trotter
I'm involved with very lossy links and low signal strengths using gmsk and dqpsk and would like to add a layer of reed-solomon encoding in place of the current CRC check. My plan was to use reed solomon in a standard (255,223) configuration and use PKSC#7 padding in 223 byte blocks where the last N
