  • Apparatus and method for SINR estimation HSDPA MIMO receiver
    Patent number: 8351555
    Abstract: In an example embodiment a method comprises receiving at least one data stream from at least two transmitter antennas, wherein the at least one data stream is pre-coded by a set of weighting coefficients; receiving a pilot channel from each of the at least two transmitter antennas; processing the received at least one data stream by an equalizer with a set of equalizer filter coefficients; calculating for each of the at least one data stream following: a signal power and an interference power from other stream, if there is any intererence, at least in part based on a set of post equalizer channel coefficients and the set of weighting coefficients; a noise power at least in part based on the received pilot channels and the set of weighting coefficients; and a signal to interference and noise ratio based on the corresponding calculated signal power, interference power and noise power.
