摘要： A radar, or other repetitive interference, detection and data flow control system and method for RF data transmissions uses an RF detector and an omni directional antenna to detect radar or similar signals. The information from the RF detector is communicated to a hub data transmission unit which processes the data about the signal provided by the detector. This information is used by the hub to schedule communications between the hub and subscriber units so that none of the communications between the hub and subscriber fall within the time period of the interfering pulses. Although there are no communications during the time periods of the pulses, the efficiency of communications is improved because collisions and retransmission of data are avoided.

摘要： The present invention is directed to a system and method which statistically determines when regularly occurring interference events of a predictable duration will occur, for example radar pulses and dynamically adjusts an automatic gain control (AGC) for RF data transmissions accordingly. The repetition rate and width of radar pulses are regular. By averaging and watching for correlations, the present AGC identifies the pulse rate and pulse widths and over a fairly short period of time predicts when the next pulse is coming. When the next pulse occurs, the AGC is adjusted to react accordingly. The AGC can raise or lower gain levels for the duration of the pulse; or ignore the pulse, if it is of a very short duration, so that the AGC level will coast through the event.

摘要： A system for mitigating the effects of interference in an unlicensed RF band for point to point data transmissions comprises a multibeam antenna locating interference with transmission to and from data transmission subscribers. A scanner determines the frequency, bandwidth and any periodicity of the interference. Separate scanners can be used for each antenna beam. Nulls are generated in the data transmission antenna pattern in the direction of the interference during periods of interference. Communications with subscribers in a direction of the interference is carried out using a different channel or is scheduled around the interference occurrences. Alternatively, such subscribers are directed to establish data transmissions with an alternate hub antenna.
