Patent ID: 7680202

Claim:
A communication system for the transfer of digital data frames on a fixed frequency channel in the presence of interference from at least one frequency hopping spread spectrum interference source, said communication system comprising a transmitter including: a time diversity generation circuit comprising: a frame data rate multiplier to receive data frames to increase a data transfer rate of at least one grouping of said data frames to time compress said groupings of said data frames; and a data frame duplicator in communication with said frame data rate multiplier to receive said time compressed groupings of data frames, and duplicate said time compressed groupings of said data frames; wherein said frame data rate multiplier increases the data transfer rate and the data frame duplicator duplicates the time compressed grouping of said data frames as a function of a transmission data rate multiplication factor and a data frame length grouping number indicative of a number of data frames included within a grouping such that the time compressed and duplicated grouping of said data frames can avoid said interference; and wherein said duplicated time compressed groupings of data frames are transmitted serially by said transmitter on a fixed frequency channel in the presence of said interference to allow reception of all time compressed groupings of data frames in spite of said interference.
