   1 2006-06-20  Eric Blossom  <eb@comsec.com>
   2
   3         * python/gmsk2/receive_path.py, python/gmsk2/transmit_path.py,
   4         benchmark_gmsk_{tx,rx}.py: refactored to use modulation
   5         independent pkt.py code.  Lays the foundation for a single set of
   6         tools that can exercise all modulations.  More work required to
   7         meet that goal, but we're closing in.
   8
   9         * python/gmsk2/tunnel.py: refactored version of
  10         tunnel_ip_null_mac.  This creates a virtual ethernet inteface
  11         using the TAP driver, and then tunnels packets across the air
  12         using GMSK and a simple carrier sense MAC.  Fixed problem with
  13         truncation of large packets which was leading to stalls.
  14
  15         * python/gmsk2/tunnel_ip_null_mac.py: removed.  Replaced with
  16         tunnel.py
  17
  18 2006-06-15  Eric Blossom  <eb@comsec.com>
  19
  20         * python/usrp/usrp_fft.py (app_flow_graph.set_decim): added
  21         missing return value.
  22
  23         * python/usrp/usrp_oscope.py, python/usrp/usrp_fft.py: you can now
  24         change the decimation factor in the GUI.
  25
  26 2006-06-06  Eric Blossom  <eb@comsec.com>
  27
  28         * python/gmsk2/mpsk.py: Lots of rework.  QPSK is now
  29         working with mpsk_test.py.   Need to confirm it on the air, and then
  30         make BPSK work again.
  31
  32
  33 2006-05-30  Eric Blossom  <eb@comsec.com>
  34
  35         Standardized on mpsk as the prefix.  Renamed a bunch of stuff to
  36         restore sanity:
  37         * python/gmsk2/benchmark_xpsk_rx.py -> python/gmsk2/benchmark_mpsk_rx.py
  38         * python/gmsk2/benchmark_xpsk_tx.py -> python/gmsk2/benchmark_mpsk_tx.py
  39         * python/gmsk2/psk_receive_path.py  -> python/gmsk2/mpsk_receive_path.py
  40         * python/gmsk2/psk_transmit_path.py -> python/gmsk2/mpsk_transmit_path.py
  41         * python/gmsk2/xpsk.py              -> python/gmsk2/mpsk.py
  42         * python/gmsk2/xpsk_pkt.py          -> python/gmsk2/mpsk_pkt.py
  43         * python/gmsk2/xpsk_test.py         -> python/gmsk2/mpsk_test.py
  44
  45 2006-05-29  Eric Blossom  <eb@comsec.com>
  46
  47         * python/gmsk2/qpsk_tester.py, python/gmsk2/qpsk_usrp_tester.py:
