The parallel search algorithm of two-component quasi-periodic minimum shift keying-binary offset carrier modulated spread spectrum signals is investigated. Suggested algorithm with a slight loss in immunity (0,9 dB) provides significant implementation advantages in compare with optimal algorithm and allows to reduce hardware rate requirements due to elimination of multiplications. The possibility of implementation in real-time mode is determined by required volume of RAM: 2(K×4N) kB (when the volume of a single cell mem- ory 2 kB); and by computing capabilities: required computation volume is determined in the first approximation by number of sum operations (4N)2.
