Abstract: A radio frequency (RF) communications system 20 may include a first RF node 22 that transmits data, including a new frequency of operation, and a sequence of pilot symbols spread with a complex spreading code sequence. A second RF node 30 may receive an incoming signal from the first RF node 22 and perform despreading for N sample offset delays to generate N despreading sequences for the sequence of pilot symbols. The second RF node 30 may perform a cross-correlation to select a desired despreading sequence from the N despreading sequences, determine a phase offset and timing offset, process the incoming signal based upon the desired despreading sequence, phase offset and timing offset, and switch to the new frequency of operation.

Abstract: The invention relates to a method and apparatus for transmitting telemetry data of an airborne vehicle (10) to a ground station (12), wherein telemetry data is obtained, a telemetry carrier is generated, the telemetry carrier is spread by a spreading factor, and the spread telemetry carrier is periodically broadcast by an antenna (26) of the airborne vehicle (10). The spreading factor depends on the difference in antenna gain of main lobe and first side lobe of the directional antenna (30) of the ground station (12). Further, a method and apparatus for receiving telemetry data of an airborne vehicle (10) by a ground station (12) are provided. The directional antenna (30) of the ground station (12) is rotated stepwise to search for telemetry data broadcast by the airborne vehicle (10). In each step the directional antenna (30) is rotated by a predetermined angle that depends on its side lobe beamwidth.
