The optical ZCZ code is a set of pairs of binary and biphase sequences with zero correlation zone. An optical M-ary direct sequence spread spectrum (M-ary/DS-SS) system using this code can detect a desired sequence without interference of undesired sequences. However, the bank of matched filters in a receiver circuit may fall into large scale. In this paper, we propose the compact construction of a bank of matched filters for an M-ary/DS-SS system using an optical ZCZ code. This filter bank can decrease the number of 2-input adders from O(N^2) to O(N) and delay circuits from O(N^2) to O(N log_2 N), respectively, and is implemented on a field programmable gate array (FPGA) corresponding to 400,000 logic gates.
