ABSTRACT:
A transmitter system that transfers digital data on a fixed frequency channel of a radio frequency band in the presence of interference from at least one FHSS interference source includes a time diversity generation circuit. The time diversity circuit compacts a duration of data frames then replicate the time compressed data frames. The duplicated time compressed frames of data are transmitted to a communication receiver that has a time diversity data recovery circuit.
