The single carrier signal transmission scheme based on channel-detecting in troposcatter communication was introduced according to the characters of the troposcatter channel. Theory analysis and performance evaluation of the troposcatter modem employing this technique were also presented. Finally

comparison between this modem and systems which adopts the best diversity combination was given

which shows highly accordance with theoretical analyzing. Be- sides

complexity of troposcatter communication systems can be greatly reduced by adopting this technique

and it has important reference for development of troposcatter communication.
