A communication 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. The time diversity data recovery circuit buffers the received compressed and replicated data frames, evaluates whether each of the duplicated time compressed data frames are received correctly. If any one of the duplicated time compressed data frames is destroyed, the copy of the destroyed duplicated time compressed data frame is used to recover the data frame.
