MIMO system estimates Ior / Ec method and a terminal device

Example discloses a MIMO system estimates Ior / Ec method and terminal apparatus of the present invention. Relates to communication technologies, without additional message exchange between the terminal device and the cells premise it is possible to obtain a more accurate estimate of Ior / Ec. The method comprising: a first pilot signal and a second despread pilot signal descrambling, obtaining at least two antennas each channel response and a noise level symbols; respectively obtaining a first noise term of the first pilot signal and a second noise term covariance second guide covariance noise term and the second pilot signal, a first pilot signal and the pilot cross-covariance between the signal noise term; antennas based on the channel response of the at least two , at least two antennas of the noise level of each symbol noise variance, covariance first, second covariance and cross-covariance is calculated at least two antennas of the respective energy signal with pilot energy ratio. MIMO system is mainly used for equalization.
