• SCP-RPSC – THE KEY TECHNOLOGY FOR THE NEXT GENERATION MICROWAVE COMMUNICATION SYSTEMS

    Machines. Technologies. Materials., Vol. 9 (2015), Issue 6, pg(s) 13-16

    A retrospective review of a new technology, named SCP-RPSC, is given in this report. It is particular useful as the radio front end of the microwave communication systems with terrestrial and satellite positioning. SCP (Spatial Correlation Processing) technology includes additional pilot signal transmitted in the band of information signals and available in the receiver by one of the known methods of radio access. The receiver terminal is equipped with random phased antenna array. The random phase spread information and pilot signals correlate in a correlator. Its output signal at baseband is the recovered information signal. The application of SCP principle in transmit mode was named RPSC (Random Phase Spread Coding). The transmitted by the random phased antenna array signals have specific phase spread. It can be considered as random spatial coding. The advantages of the SCP-RPSC approach over classic microwave communication systems, based on phased antenna arrays, are shown. A list of possible communication applications as Satellite Digital Video Broadcasting , Inter Satellite Links, Feeder Lines, High Altitude Platform Systems, WIMAX, Aeronautical and Global Navigation Satellite Systems (GNSS) is given too.
