MULTI-CARRIER SPREAD SPECTRUM DEVICE USING CYCLIC SHIFT ORTHOGONAL KEYING, TRANSMITTER, RECEIVER, AND COMMUNICATION SYSTEM THEREOF
摘要:
A multi-carrier spread spectrum device using cyclic shift orthogonal keying includes: a modulation unit for receiving a first part of data bits and transforming the first part of data bits to a modulation symbol di by modulation; a cyclic-shift unit for receiving a base code c(0) and a second part of data bits, and performing a cyclic-shift to the base code c(0) in accordance with the second part of data bits to generate a CSOK symbol c(mi); and a multiplier for multiplying the modulation symbol di by the CSOK symbol c(mi) to generate a spread spectrum signal ci.
