ABSTRACT:
A tropospheric scatter radio communication system uses a multiple signal diversity system in order to improve reliability of reception. A dual time diversity is used in which adjacent bits in a digital word are interleaved with bits from adjacent digital words so that more than one bit from a particular digital word is unlikly to be adversely affected by short term fading.
