METHOD AND SYSTEM FOR PROVIDING WIRELESS COMMUNICATION AND LOCATION MEASUREMENT BY USING DIFFERENTIALLY BI ORTHOGONAL CHIRP SHIFT KEYING

摘要

The present invention relates to a method and apparatus for wireless communication and position measurement using differential binary orthogonal shifting.;The present invention can be received by a receiver having a simple structure by modulating a chirp shift keying signal with a differentially orthogonal function or a differentially biorthogonal function to use in communication. By changing the combination order and direction of the Chirp Shift Keying signals, you can obtain quasi orthogonality between the Chirp Shift Keying signals, thus minimizing interference even if different transmitter receivers use the Chirp Shift Keying signals simultaneously. The advantage is that you can.;Orthogonal Modulation, Differential Encoding, Orthogonal Function, Differential Decoding, Time Interval Difference, Orthogonal Signal
