What are the options for doing MIMO with, say 16 receviers?
You would need to design and build some kind of hub

Collisions are still very likely in a software-defined radio

Hi,
I am testing the carrier sense mechanism on USRP based on code from
benchmark_tx.py and tunnel.py. My scenario is to receive packets from two
distinctive nodes simultaneously at the third node. I am prefixing the
payload with sender node name to identify the sender.

A fair amount of the RF-specific resources there are textbooks I don't have
access to, though it's probably a transmission issue, honestly. However, the
code consists a modified version of gr_sig_source_c (saved under an
alternate name) and usrp_siggen.py, with hard-coded values for all wave

This post is a bit old... but I'm having a similar problem. Created a
modified gr_sig_source_c block such that attributes are assigned by
pseudo-randomly generated numbers (restricted to ranges such as would be
proper, as well as swapping waveform types for integers 0-5 and randomly
assigning one)

This likely a bug in the host driver for the USRP2;
For both those functions you need to pass in the variable you want assigned the
value as an input parameter.
Look at gnuradio/trunk/gr-usrp2/src/usrp2_source_base.cc for the function
definitions of adc_rate and daughterboard_id.
