FIELD: information technologies.
SUBSTANCE: signals are detected in several stages using correlation in time domain for the first stage, processing in frequency domain for the second stage and processing in time domain for the third stage. Products of symbols are formed for the first stage, at least for two different delays, correlation is carried out between products for each delay and available values, and results of correlation for all delays are combined and used to announce the signal availability. For demodulation, synchronisation of input samples is adjusted to produce time-adjusted samples. Frequency deviation is assessed and removed from time-adjusted samples to produce samples with frequency correction, which are processed with the help of channel assessment to produce detected symbols. Phases of detected symbols are corrected to produce symbols with phase correction, which are demodulated, alternated backwards and decoded.
EFFECT: provision of wireless communication network and station, functioning with expanded coverage range.
