一组具有零相关区的序列称为ZCZ码，可以为CDMA系统提供无干扰性能，称为ZCZ-CDMA。具有稍大的零相关区的ZCZ码，其中族大小达到数学上界，可以用于在恶劣的信道环境中提供具有高稳定性和传输效率的CDMA系统。本文设计了一种具有上述特性的p相ZCZ码匹配滤波器组（MFB），它可以同时对接收符号序列和ZCZ码中的每个序列进行相关运算，并且可以用最少的电路元件来设计。MFB将提供一个ZCZ-CDMA模块，它可以灵活地构成一个网络系统，因为它可以同时检测所有的数据比特，并可以利用它们。
A set of sequences with a zero correlation zone named as a ZCZ code can provide CDMA systems with interference free performance called ZCZ-CDMA. A ZCZ code with the slightly large zero correlation zone, in which family size reaches the mathematical upper bound, may be used to offer a CDMA system with high stability and transmission efficiency in inferior channel environment. This paper designs a matched filter bank (MFB) of p-phase ZCZ codes with the above properties, which can simultaneously take correlation between a received symbol sequence and every sequence in the ZCZ code, and can be designed by the minimum number of circuit elements. The MFB will provide a ZCZ-CDMA module which can construct a network system flexibly, since it can detect all data bits at the same time and can utilize them.
