FIELD: physics, communication. ^ SUBSTANCE: invention concerns wireless communication, namely, to improvement of estimate of noise. Noise measurings are carried out during a part of one continuance of the longest figure of an orthogonal code. The processor (520) guidances identify an unoccupied code with small coefficient of expansion. The device (512) squeezings measures energy of a figure on the basis of an unoccupied code, and the device (516) estimates of noise shapes estimates of noise on the basis of the measured energies of figures. ^ EFFECT: improvement of estimate of noise. ^ 22 cl, 6 dwg |
