Summary: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.
