FIELD: information technology.
SUBSTANCE: noise evaluation can be done for each packet received during data transmission. Data for each packet can then be detected using the noise evaluation for each packet. To evaluate noise, a first sequence of samples and a second sequence of samples may be obtained from each receiver used to receive data. Phase shift between the first and second sequences of samples can be determined and applied to the first sequence of samples for each receiver to obtain a third sequence of samples for that receiver. Noise evaluation can then be obtained based on the power of differences between the second and third sequences of samples for at least one receiver.
EFFECT: higher accuracy of determining noise value.
