    Abstract: An arrangement is provided for using 2's complement arithmetic without the high switching activity of the prior art. In particular, the invention operates to exploit the sign-extension property of a 2's complement number. A reduced representation for 2's complement numbers is provided to avoid sign-extension and the switching of sign-extension bits. The maximum magnitude of a 2's complement number is detected and its reduced representation is dynamically generated to represent the signal. A constant error introduced by the reduced representation is also dynamically compensated.

    Abstract: A method and apparatus are disclosed for increasing the effective processing speed of a parallel decision-feedback equalizer (DFE) by combining block processing and look-ahead techniques in the selection (multiplexing) stage. The present invention extends a parallel DFE by using look-ahead techniques in the selection stage to precompute the effect of previous blocks on each subsequent block, and to thereby remove the serial output dependency. The parallel DFE includes a multiplexor tree structure that selects an appropriate output value for each block and precomputes the effect of previous blocks on each subsequent block. A multiplexing delay algorithm on the order of logN is employed to resolve the output dependency and thus speeds up parallel block processing DFEs. The disclosed DFE architecture can be combined with pipelining to completely eliminate the critical path problem. Pipelining reduces the required critical path timing to one multiplexing time. The disclosed multiplexor tree circuitry for the parallel DFE groups multiplexor blocks into groups of two, referred to as block pairs, and provides at least one multiplexor for each block, i, to select an output value, yi, from among the possible precomputed values. The output of each parallel block depends on the possible precomputed values generated by the look-ahead processors for the block, as well as the actual values that are ultimately selected for each previous block. In order to reduce the delay in obtaining each actual output value, the present invention assumes that each block contains each possible value, and carries the assumption through to all subsequent blocks. Thus, the number of multiplexors required to select from among the possible values grows according to N·logN, where N is the block number.

More particularly, this invention relates to halogenated polypeptides having at least one haloalanine-like amino acid, and methods for their preparation which involve converting the hydroxyl group (i.e., --OH) of a serine-like amino acid to a halo group (i.e., --X where X is Cl, Br, or I) with the aid of a phosphorus-based halogenation reagent such as a triphenylphosphine dihalide (i.e., (C.sub.6 H.sub.5).sub.3 PX.sub.2, wherein X is Cl, Br, or I), a triphenylphosphite dihalide (i.e., (C.sub.6 H.sub.5 O).sub.3 PX.sub.2, wherein X is Cl, Br, or I), or a mixture of triphenylphosphine or triphenylphosphite with a halohydrocarbon (i.e., "halo-conversion"). This invention also relates to cyclic polypeptides having at least one polypeptide loop comprising a thioether linkage, and methods for their preparation which employ halogenated polypeptides and which involve intramolecular alkylation of the thiol group of a cysteine-like amino acid by the halo group of a haloalanine-like amino acid under suitable basic conditions to form a thioether linkage (i.e., "cyclization").

    Abstract: Convergence of blind fractionally spaced equalizers is improved, and misconvergence is corrected by training the equalizers to detect convergence of one adaptive filter, copying the tap weights of the converged adaptive filter to the other adaptive filters and shifting the tap weights of the other adaptive filters according to the expected phase difference between the respective filters. In a two-dimensional orthogonal modulation scheme the converged weights of a first filter are copied to a second filter and shifted .pi./2. For the two dimensional orthogonal modulation scheme, the probability of a proper convergence can be increased by choosing initial tap weights for the two adaptive filters with a 3.pi./4 phase difference.
