摘要/Abstract

摘要： 提出了一种采用双正交循环码的M元扩频接收机方案．在发送端，每个用户采用双正交循环码实现M元扩频，而接收机利用一个变换域匹配滤波器就可完成M元扩频信号的解扩．与传统的M元扩频系统相比较，该方案有效地降低了M元扩频系统的复杂度和选码的难度．

Abstract: A novel M-ary spread spectrum receiver using biorthogonal cyclic codes is proposed. In the transmitter, every user uses biorthogonal cyclic codes to realize the spreading spectrum, and the proposed receiver can achieve despreading with only one transform domain matched-filter. Compared with the traditional M-ary spread spectrum system, the proposed scheme effectively reduces the computation complexity and the PN codes selection difficuly of the M-ary spread spectrum system.

Key words: M-ary spread spectrum, biorthogonal cyclic codes, transform domain processing
