Abstract
A method for processing radio-frequency signals received on R antennas, where R≥2, includes, implemented by a radio unit: obtaining a frequency representation of the radio-frequency signal received on an antenna, demapping the frequency representations, first estimation of the transmission channel of the radio-frequency signals and of a noise-plus-interference covariance, projecting a vector of R complex samples onto a vector of L complex samples, referred to as projected samples, transmitting the vector of L projected samples to a base band processing unit, as well as the following, implemented by the base band processing unit: receiving the vector of L projected samples transmitted by the radio unit, demapping the L projected samples, second estimation of the transmission channel of the radio-frequency signals, after projection, equalising the L projected samples, taking account of the second channel estimation, processing the equalised symbols.
