Dear all: Now, I am running the benchmark_tx.py and benchmark_rx.py
on the USRP E110s. However, even if I set the bit rate to 100khz and
use bpsk modulation scheme, overflow always occure. I get some
information that benchmark examples now can not work well in the USRP
E110. So, is there some one run benchmakr examples well in the E110
or is there some suggestion to solve this overflow problem.
Well I suspect the bandedge fll in the bpsk chains takes up a little too
much juice. I might suggest experimenting with the gmsk chains.
Anyway, this is expected. benchmark is an example of implementing a mac
layer w/ gnuradio in python. But its not going to yield continuous
high-rate throughput.
When you code up your application, I suggest making heavy use of the
neon SIMD. :-)
