FIELD: information technologies.
SUBSTANCE: detection information of a wireless system and system definition is modulated with pseudorandom sequences. R bits of information carried by a detection pilot signal, which carry information of the system definition, are expanded with T bits, which carry index of counter associated with system time characteristics of super-frames sent from the access point. Non-productive costs for treatment caused by addition of T bits are compensated with advantages provided in the wireless communication, such as the following: (i) win of processing in a receiver for communication in a specific sector during asynchronous transmission, (ii) determination of packet borders by means of the counter field values and (iii) initialisation of various pseudo-random registers used for communication.
EFFECT: improved efficiency of pilot signals detection, which may carry information of time and frequency synchronisation.
