ABSTRACT:
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 diby 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 diby the CSOK symbol c(mi)to generate a spread spectrum signal ci.
