FIELD: information technology.
SUBSTANCE: wireless communication device configured to reduce false alarms in a communication system comprises a processor configured to generate a sequence of signal elements using a structured code and interleaving the sequence of signal elements before transmission. The sequence of signal elements is interleaved by recording the sequence of signal elements into a pseudorandomly selected signal element cells, and a memory device connected to the processor; wherein the processor maps a message to one Walsh code from a plurality of Walsh codes, wherein the structured code is that Walsh code to which the message is mapped.
EFFECT: reduced false alarms due to Doppler shift in a wireless communication system.
