Patent ID: 7555031

Claim:
A time diversity data recovery circuit within a communication receiver comprising: a diversity receiver to receive duplicated time compressed data frames that are transmitted on a fixed frequency channel in the presence of interference from at least one frequency hopping spread spectrum interference source and extract the duplicated time compressed data based on a transmission data rate multiplication factor and a data frame length grouping number; a data frame buffer in communication with said diversity receiver to receive said transmission data rate multiplication factor and said data frame length grouping number to allocate buffer locations within said data frame buffer and to receive said duplicated time compressed data frames; and an error detection and correction circuit in communication with said data frame buffer to retrieve sequentially said duplicated time compressed data frames, to evaluate whether each of said duplicated time compressed data frames are received correctly and if not received correctly whether they have been destroyed by said interference, if any one of said duplicated time compressed data frames is destroyed retrieving a copy of said destroyed duplicated time compressed data frame to recover said data frame; wherein data frame buffer orders said duplicated time compressed data frames in order locations to allow ordered retrieval of said data frames by said error detection and correction circuit; wherein said transmission data rate multiplication factor is determined by number of data frames obstructed by said interference and a bandwidth of said interference.
