Hello,
I've had a rather enjoyable time having a play with gnuradio over the holidays. Well done to the contributors!
I'm interested in contributing a bit but I would like some guidance so as not to trample on anyone's territory :-)
Channel Coding:
1. Phil Karn's Reed-Solomon code is in the 2.6 tarball but I can't find
any blocks that use it. Have I missed something? Does the RS stuff need
wrapping in a gr_block?
2. Also, Phil Karn's convoltional code/decoders are also available in the GPL. Is anyone wrapping these in blocks yet?
TDMA:
3. How do the designers envisage doing TDMA? Is it a case of
documenting techniques that enable the designer to get gnuradio to do
what you need? I'm thinking in particular:
- Attaching meta-information (e.g. timestamps, error measurements) to blocks of samples
- Zero-copy methods (e.g. for muxes)
4. Is anyone working on a gr_soft_correlator that does something
similar to gr_simple_corrlator but in the over-sampled, soft-decision
domain?
Cheers,
