    • A method for timing and frequency synchronization in a wireless system is provided. The method comprises the steps of receiving a burst of symbols, selecting a subset of the burst of symbols, iteratively adjusting the subset of the burst of symbols by a plurality of timing offsets and calculating, for each timing offset, a first performance metric corresponding to the adjusted subset. The method further comprises the steps of determining one of the plurality of timing offsets to be a preferred timing offset based upon the first performance metric thereof, iteratively rotating the subset of the burst of symbols by a plurality of frequency offsets and calculating, for each frequency offset, a second performance metric corresponding to the rotated subset, and determining one of the plurality of frequency offsets to be a preferred frequency offset based upon the second performance metric thereof.

    • The invention relates to a method and a system for magnetic induction tomography, the system comprising: at least one transmitting coil (312, 314) for generating a primary magnetic field to be applied to the object of interest (301); and at least one measurement coil arrangement (315, 317) for measuring electric signals induced by a secondary magnetic field which is generated by the object of interest in response to the primary magnetic field, wherein the at least one measurement coil arrangement comprises a plurality of measurement coils which are positioned in substantially the same plane. By using a plurality of independent measurement coils positioned in a plane so as to replace a conventional single measurement coil, the measurement coil across which the measured difference voltage is most sensitive to a change of the secondary magnetic field can be selected for calculating the change of conductivity distribution, resulting in an improved sensitivity of a MIT system.

    • The invention relates to a coil arrangement comprising at least one transmitting coil for generating a primary magnetic field; and a plurality of measurement coils; wherein the at least one transmitting coil (408, 409) and the plurality of measurement coils (410, 411) are arranged in such a way that the flux curve of the primary magnetic field generated by a transmitting coil (409) among said at least one transmitting coil (408, 409) passes into and out of a first measurement coil (410) among said plurality of measurement coils (410, 411), the first measurement coil being the coil closest to the transmitting coil. By enabling the flux of the primary magnetic field to pass into and out of a first measurement coil, the signal induced on the first measurement coil by the positive and negative flux can be compensated, resulting in a reduction of the signal strength of the induced signal on the measurement coil and the signal dynamic range.
