    Abstract: The present invention is directed to a coil assembly capable of producing a flexible FOV for use with an MRI system. The coil assembly includes a gradient coil disposed about an imaging axis and a plurality of higher order gradient coils, or shim coils, positioned about the primary gradient coil such that the plurality of higher gradient order coils have a radius greater than the radius of the primary gradient coil. A change in the FOV is realized by modulating the current in the higher order gradient coils or shim coils.

    Abstract: The invention relates to calculating an estimate representing noise and signal quality, and to a receiver of a radio system. The highest value of a correlation vector is compared either to the second highest value or to the mean value of the other values. If a specific spreading code is used in the reception of the signal, the comparison forms a ratio of the signal and disturbance, the ratio being applicable particularly to combining signals from the diversity branches of a diversity receiver, whereby the method makes it possible to combine the signals even prior to detection. If the reception employs a spreading code with which no signal received by the receiver has been transmitted, it is possible by comparing the correlation values to form a noise quality estimate, an estimate value higher of which meaning that the receiver is receiving a signal and not just noise.

Within the downlink sub-frame, interposed between sub-frames are guard intervals that have known sequences positioned therein. The known sequences are used for an estimation of a received power. A method comprising the step of using a guard sequence in a guard interval of OFDM symbols of the received TDS-OFDM signals in the downlink or the uplink to estimate a received signal power and using the estimated signal power to calculate a CINR is provided.
