Multi-carrier spread spectrum device using cyclic shift orthogonal keying, transmitter, receiver, and communication system thereof
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 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.
Abstract(Chinese):

使用循环移位正交键控的多载波扩频装置包括：调制单元，用于接收数据比特的第一部分，并通过调制将数据比特的第一部分变换成调制符号di; 循环移位单元，用于接收基本代码c（0）和第二部分数据位，并且根据第二部分数据位对基本代码c（0）执行循环移位，以产生CSOK符号 c（mi）; 以及用于将调制符号di乘以CSOK符号c（mi）的乘法器，以生成扩频信号ci。
