   4
   5 2006-06-20  Eric Blossom  <eb@comsec.com>
   6
   7         * python/gmsk2/receive_path.py, python/gmsk2/transmit_path.py,
   8         benchmark_gmsk_{tx,rx}.py: refactored to use modulation
   9         independent pkt.py code.  Lays the foundation for a single set of
  10         tools that can exercise all modulations.  More work required to
  11         meet that goal, but we're closing in.
  12
  13         * python/gmsk2/tunnel.py: refactored version of
  14         tunnel_ip_null_mac.  This creates a virtual ethernet inteface
  15         using the TAP driver, and then tunnels packets across the air
  16         using GMSK and a simple carrier sense MAC.  Fixed problem with
  17         truncation of large packets which was leading to stalls.
  18
  19         * python/gmsk2/tunnel_ip_null_mac.py: removed.  Replaced with
  20         tunnel.py
  21
  22 2006-06-15  Eric Blossom  <eb@comsec.com>
  23
  24         * python/usrp/usrp_fft.py (app_flow_graph.set_decim): added
  25         missing return value.
  26
  27         * python/usrp/usrp_oscope.py, python/usrp/usrp_fft.py: you can now
  28         change the decimation factor in the GUI.
  29
  30 2006-06-06  Eric Blossom  <eb@comsec.com>
  31
  32         * python/gmsk2/mpsk.py: Lots of rework.  QPSK is now
  33         working with mpsk_test.py.   Need to confirm it on the air, and then
  34         make BPSK work again.
  35
  36
  37 2006-05-30  Eric Blossom  <eb@comsec.com>
  38
  39         Standardized on mpsk as the prefix.  Renamed a bunch of stuff to
  40         restore sanity:
  41         * python/gmsk2/benchmark_xpsk_rx.py -> python/gmsk2/benchmark_mpsk_rx.py
  42         * python/gmsk2/benchmark_xpsk_tx.py -> python/gmsk2/benchmark_mpsk_tx.py
  43         * python/gmsk2/psk_receive_path.py  -> python/gmsk2/mpsk_receive_path.py
  44         * python/gmsk2/psk_transmit_path.py -> python/gmsk2/mpsk_transmit_path.py
  45         * python/gmsk2/xpsk.py              -> python/gmsk2/mpsk.py
  46         * python/gmsk2/xpsk_pkt.py          -> python/gmsk2/mpsk_pkt.py
  47         * python/gmsk2/xpsk_test.py         -> python/gmsk2/mpsk_test.py
  48
  49 2006-05-29  Eric Blossom  <eb@comsec.com>
  50
  51         * python/gmsk2/qpsk_tester.py, python/gmsk2/qpsk_usrp_tester.py:
  52         new.  Test benches for qpsk code. Thanks Tom!
