Method and apparatus for motion-compensated noise evaluation, in the case of mobile wireless transmission systems

摘要

A method for motion-compensated noise evaluation in mobile wireless transmission systems, in which from a transmitter (1) reference symbols (14, 16) are transmitted with the following features:– that is composed of at least a part of temporally means - or directly in succession in a receiver (2) of received reference symbols (s_–1, s_–2, s_–3) by means of the formation of a statistical torque, a static component (s_{configuration}) the received reference symbols (s_–1, s_–2, s_–3) is determined;– that a dynamic share (s_motion) the received reference symbols (s_–1, s_–2, s_–3) by comparison of at least two means - or directly temporally successive reference symbols (s_–μ, s_–1) is determined;– that from the static (s_{configuration}) and the dynamic component (s_motion) the received reference symbols (s_–1, s_–2, s_–3) a prediction value {overscore (s) (s_pred) for the next received reference symbol { (s₀) is calculated;– that after the reception of the next reference symbol (s₀) by comparing this received reference symbol (s₀) with the prediction value {overscore (s) (s_pred) a prediction error {overscore ( (s_err) it is determined;– that from the prediction error (s_err) an estimated value..
