FIELD: information technologies. ^ SUBSTANCE: methods are disclosed for detection and demodulation of data transfers in systems of wireless communication. In one aspect, detector with control by decision detects transfers of data in received signal, using received symbols of data and also received symbols of pilot-signal. Detector with control by decision may be intended to do differential detection in frequency domain or coherent detection in time domain, and may be used in modulation with multiple carriers (for instance, OFDM). In another aspect, adaptive threshold is used to detect received data transfers. Threshold may be detected for each hypothetically received transfer of data. Threshold may be calculated, for instance on the basis of signal and noise energy of hypothetical data transfer. ^ EFFECT: increased efficiency of detection. ^ 37 cl, 17 dwg, 1 tbl |
