The method comprises generating a plurality of test sequences, determining an order for the plurality of test sequences, such that each test sequence differs from its adjacent test sequences by a respective predefined number of bits, and carrying out a maximum likelihood process with the ordered test sequences and the input data sequence thereby generating a maximum likelihood sequence.

A method for spectrum sensing is described comprising receiving a signal using a plurality of receive antennas; forming a set of received signals including the received signal of each antenna; determining a cyclic auto-correlation of the set of received signals; estimating, for each receive antenna, channel state information of the radio channel via which the receive antenna receives the signal based on the determined cyclic auto-correlation; performing maximum ratio combining of the received signal samples based on the estimated channel state information; determining a measure of the cyclostationarity of the received signal based on the result of the maximum ratio combining; and performing cyclostationarity detection spectrum sensing based on the determined measure of the cyclostationarity of the received signal.

The present invention relates to titanium catalysts for synthesis reactions produced by bringing a reaction mixture comprising a titanium alkoxide and a ligand in contact with water, wherein the ligand is represented by the general formula (e): wherein R1, R2, R3, and R4 are independently a hydrogen atom, an alkyl group, or the like, and (A) represents a group with two or more carbon atoms. The titanium catalysts may be isolated in solid form and may be stored. The invention further relates to a process for cyanation of imines, wherein the process comprises reacting an imine with a cyanating agent in the presence of the titanium catalyst.

A sensor for measuring gas permeability of a test material, comprising: an electrically conductive sensing element that comprises a water and/or oxygen sensitive material, wherein the reaction of said material with water or oxygen when the sensing element is contacted with water and/or oxygen results in a change in the electrical conductivity of the sensing element, and two electrodes electrically connected to the sensing element.

According to embodiments of the present invention, a method of processing a wafer is provided. The wafer includes a plurality of through-wafer interconnects extending from a frontside surface of the wafer to a backside surface of the wafer. The method includes removing a part of wafer material of the back-side such that a portion of the wafer material between the through-wafer interconnects is removed, thereby exposing a portion of the through-wafer interconnects, forming a layer of low-k dielectric material between the through-wafer interconnects, and planarizing the layer of low-k dielectric material such that a surface of the portion of the through-wafer interconnect is exposed.
