    摘要： Method and apparatus for generating ternary and multi-valued Gold sequences, are disclosed. Also methods to detect ternary and multi-valued sequences are disclosed. The detection can be performed by a ternary or multi-valued LFSR descrambler when the sequences are generated by an LFSR based sequence generator. A wireless system which can assign additional sequences to designated users is also disclosed. The wireless system can also transfer information to user equipment that enables methods for sequence generation and sequence detection.

    摘要： Multi-valued or n-state with n=2p Linear Feedback Shift Registers (LFSRs) in binary form are provided for scramblers, descramblers and sequence generators using addition and multiplication functions over a Finite Field GF(n) in binary form. N-state switching functions in an LFSR are implemented by using implementations of reversible binary functions. LFSRs may be in Fibonacci or in Galois configuration. N-state LFSR based sequence generators in binary form for generating an n-state maximum length sequence in binary form are also provided. A method for simple correlation calculation is provided. Communication systems and data storage systems using the LFSRs are also disclosed.

    摘要： The invention relates to a process for the production of diols with a special structure which are characterized by formula (I). These diols are substances which, besides two OH groups, contain a C═C double bond so that they are suitable as monomers for the production of polymers. The process comprises hydrolyzing a corresponding cyclic precursor in aqueous medium in the presence of an acid dissolved in that medium, the hydrolysis being accompanied by the elimination of a carbonyl compound, and subsequently neutralizing the acid present in the reaction mixture with a base, the base having a pKb value above 0.18 and preferably above 3.0 and being present in heterogeneous form.
