**Abstract: **A problem of search
algorithm for spread spectrum signal is considered in the paper. The spread
spectrum signal is direct spread of minimum frequency shift keying (MSK)
signal. The probability analysis of spread spectrum search detector is
performed. Using obtained equations the estimation of missing and alarm probabilities
are calculated.

**Key words:** spread spectrum signal,
search algorithm, synchronization, energy detector, alarm probability, missing
probability.
