2006-06-20 Eric Blossom <eb@comsec.com>
* python/gmsk2/receive_path.py, python/gmsk2/transmit_path.py,
benchmark_gmsk_{tx,rx}.py: refactored to use modulation
independent pkt.py code. Lays the foundation for a single set of
tools that can exercise all modulations. More work required to
meet that goal, but we're closing in.
* python/gmsk2/tunnel.py: refactored version of
tunnel_ip_null_mac. This creates a virtual ethernet inteface
using the TAP driver, and then tunnels packets across the air
using GMSK and a simple carrier sense MAC. Fixed problem with
truncation of large packets which was leading to stalls.
* python/gmsk2/tunnel_ip_null_mac.py: removed. Replaced with
tunnel.py
2006-06-15 Eric Blossom <eb@comsec.com>
* python/usrp/usrp_fft.py (app_flow_graph.set_decim): added
missing return value.
* python/usrp/usrp_oscope.py, python/usrp/usrp_fft.py: you can now
change the decimation factor in the GUI.
2006-06-06 Eric Blossom <eb@comsec.com>
* python/gmsk2/mpsk.py: Lots of rework. QPSK is now
working with mpsk_test.py. Need to confirm it on the air, and then
make BPSK work again.
2006-05-30 Eric Blossom <eb@comsec.com>
Standardized on mpsk as the prefix. Renamed a bunch of stuff to
restore sanity:
* python/gmsk2/benchmark_xpsk_rx.py -> python/gmsk2/benchmark_mpsk_rx.py
* python/gmsk2/benchmark_xpsk_tx.py -> python/gmsk2/benchmark_mpsk_tx.py
* python/gmsk2/psk_receive_path.py -> python/gmsk2/mpsk_receive_path.py
* python/gmsk2/psk_transmit_path.py -> python/gmsk2/mpsk_transmit_path.py
* python/gmsk2/xpsk.py -> python/gmsk2/mpsk.py
* python/gmsk2/xpsk_pkt.py -> python/gmsk2/mpsk_pkt.py
* python/gmsk2/xpsk_test.py -> python/gmsk2/mpsk_test.py
2006-05-29 Eric Blossom <eb@comsec.com>
