    • A method for de-spreading spread data includes receiving a data stream by multiple access communication where the received data stream is spread using a pseudo-noise (PN) code; multiplying a first portion of the received data stream including data from a first user by a first portion of a PN signal to obtain a first product; providing the first product to a first counter; multiplying a second portion of the received data stream including data from a second user by the first portion of the PN signal to obtain a second product; providing the second product to a second counter; and determining whether the first portion of the PN signal and the second portion of the PN signal produce valid sequences based at least in part on the first product and the second product.
    • 解扩展扩展数据的方法包括:使用伪噪声(PN)码在接收到的数据流进行扩频的多址通信中接收数据流; 将包括来自第一用户的数据的接收数据流的第一部分乘以PN信号的第一部分以获得第一乘积; 将第一个产品提供给第一个柜台; 将包括来自第二用户的数据的接收数据流的第二部分乘以PN信号的第一部分以获得第二乘积; 将第二产品提供给第二柜台; 以及确定所述PN信号的第一部分和所述PN信号的第二部分是否至少部分地基于所述第一乘积和所述第二乘积产生有效序列。
