b method and apparatus for determining the ratio between the powers of signal and interference more ruu00ecdo (SINR) in a communications system d signs of trajectory variable that comprise eachSymbols are multiplexed by time division including known symbols constituting a reference signal, are combined with respective weights to reduce CO channel interference.The weights are determined from a correlation matrix and a vector of correlation of reference signal.Using a moving window that starts with the symbols of synchronization and / or symbols CDVCC (color coded digital verification code) as the symbols are known.The SINR (ratio between signal and interference plus noise) is determined for each position of the window from elements of the correlation matrix and the vector of correlation of reference signal.The SINRs certain are the averages calculated over the period of time during various time intervals and for which trajectories are a precise determination of SINR variables.Within a period of time.The SINR provides a reliable signal quality parameter that is useful in a cellular communications system for procedures such as connection, adaptive channel allocation.Dynamic control of power and sequ00b3enciamento cells.
