Using precoded space multiplexing of limited fed back, the method defines a group of set of precoded matrix (i.e. precoded codebook) known by transmitter and receiver. Using algorithm of channel estimation to obtain current state information of channel, the receiver selects an optimal precoded matrix from precoded codebooks according to minimized principles of trace of mean square error matrix as well as through a feedback channel, feeds index of the precoded matrix back to the transmitter within coherence time of channel. Based on the said index of the precoded matrix, the transmitter obtains the precoded matrix, and then carries out precoded operations on vectors of transmit signal based on the precoded matrix. Precoded codebook can be designed based on maximized principle of minimum distance between two norms of projections of subspaces. Using limited bit number fed back, the invention raises communication performance.

An algorithmic soft-decision decoding method for Reed-Solomon codes proceeds as follows. Given the reliability matrix Pi showing the probability that a code symbol of a particular value was transmitted at each position, computing a multiplicity matrix M which determines the interpolation points and their multiplicities. Given this multiplicity matrix M, soft interpolation is performed to find the non-trivial polynomial Q<HIL><PDAT>M< / SB><PDAT>(X,Y) of the lowest (weighted) degree whose zeros and their multiplicities are as specified by the matrix M. Given this non-trivial polynomial Q<HIL><PDAT>M< / SB><PDAT>(X,Y), all factors of Q<HIL><PDAT>M< / SB><PDAT>(X,Y) of type Y-f(X) are found, where f(X) is a polynomial in X whose degree is less than the dimension k of the Reed-Solomon code. Given these polynomials f(X), a codeword is reconstructed from each of them, and the most likely of these codewords selected as the output of the algorithm. The algorithmic method is algebraic, operates in polynomial time, and significantly outperforms conventional hard-decision decoding, generalized minimum distance decoding, and Guruswami-Sudan decoding of Reed-Solomon codes. By varying the total number of interpolation points recorded in the multiplicity matrix M, the complexity of decoding can be adjusted in real time to any feasible level of performance. The algorithmic method extends to algebraic soft-decision decoding of Bose-Chaudhuri-Hocquenghem codes and algebraic-geometry codes.< / PTEXT>

A method for generating a 3D model for a restoration is operative in a computer having a display. The method begins by obtaining a 3D model of the preparation. The preparation model may be obtained by an operator using a 3D digitizer. A “margin” curve on the preparation model is then determined. The method then continues by selecting a given 3D restoration cap model from a set of such models, where the set includes cap models that vary by one or more characteristics such as type, age, sex and ethnicity. The restoration cap model has a cap edge curve. According to the invention, the method then continues by fitting the restoration cap model over the preparation model (on the computer display) so that a minimum distance between the restoration cap and the restoration model is greater than a given minimum material thickness. The restoration cap model is then reshaped or otherwise scaled as necessary so that the restoration cap edge curve is related to the margin curve in a predetermined manner. In particular, preferably the cap edge curve is related to the margin curve by an angle from vertical that is equal or substantially equal to a given emergence angle at each point along the curve. To complete the model, a side surface is then created, preferably by lofting a surface from the margin curve to the cap edge curve.
