摘要

1. An apparatus and method for optimal estimation of distortion introduced by the transmission medium, wherein said evaluation is performed by sequentially sending pairs of quadrature complementary sequences, said apparatus and method are based on the use of complementary sequences sequentially transmitted over the physical medium and separated in time, the demodulation and their subsequent adjustment allows to obtain the spectral and temporal characteristics of the environment at the reception, which allows smart shit impact shuma.2. An apparatus and method for optimal estimation of distortion introduced by the transmission medium, performed by sequentially sending pairs of quadrature complementary sequences according to claim 1, characterized in that the apparatus includes at least the following components: A) transmitting system comprising the following components: an encoder ( 2) with complementary sequences and a convolution filter, quadrature modulator (4), the frequency converter (up-converter) (6); a transmitter (7) with antennoy.V) reception system, comprising the following uyuschie components: a frequency converter (down-converter) (9), quadrature demodulator (11), the compensation noise filter (13), a decoder (15) .3. An apparatus and method for optimal estimation of distortion introduced by the transmission medium, performed by sequentially sending pairs of quadrature complementary sequences according to claims 1 and 2, characterized in that the transmission system A) generates a digital signal (1) of the preamble transmitted on the physical medium, and consisting at least 4 pulses Kronecker delta (δ (n)) p
