Nice work Joe and Domenico. Thanks for linking the wav files, I downloaded and reproduced the three decodes using the Linux decoder to get exactly the same results. I wanted to see if normalising for amplitude variation made any difference with the LF signals. It didn't, the background noise is very constant so there is negligible normalisation effect. > not bad for a message of 63 characters on LF sent in less > than 30 minutes ! The 02:00 decode: -39.6dB in audio bandwidth, 2.3 characters per minute, 62% of channel capacity. Domenico, if you want to upload the unsuccessful wavs, I can check them to see how far short of a decode they were. -- Paul Nicholson -- |
