Hi Paul, Am 01.04.2016 13:51, schrieb Paul Nicholson: So maybe this is an improvement for the next version of EbNaut: Automatic optimised list length setting, depending on the message length?For 2 char messages with 16 bit CRC, the max useful list length is probably around 1k but I don't yet know where the optimum is. Beyond a certain length (corresponding to nearly 3dB gain from the outer code) further list length increases the false hit probability as much as genuine decode probability so there is no further gain to be had (without invoking operator cognition as a 3rd layer to the coding). Also bought a kite but that's for another thread. Which kite? What are the plans?I wonder why not any ham has a kite in northern UK for MF/LF/VLF transmissions. 73, Stefan |
