摘要： Composite ghost cancellation reference (GCR) signals that make available both a chirp and a PN sequence during the same vertical-blanking-interval (VBI) scan line in each successive field facilitate more rapid and efficient calculations of ghost cancellation and of equalization, on a continuing basis. A television receiver for use with such composite GCR signals includes circuitry for separating the chirp and PN sequence portions of the GCR signals from the remainder of the composite video signal, a ghost cancellation filter and an equalization filter connected in cascade to respond to the composite video signal and provided each with adjustable filtering weights, and a computer. Random-access memory addressed during writing snatches the vertical-blanking-interval scan lines selected to include GCR signals. Sets of four successive ones of the selected scan lines are then additively and subtractively combined to separate the chirp portions of the GCR signals from a remainder of the composite video signal. The sets of selected scan lines are additively and subtractively combined in another way to separate the PN sequence portions of the GCR signals form a remainder of the composite video signal. The computer responds to the separated chirp portions of the GCR signals to calculate a discrete Fourier transform (DFT) therefrom. The computer proceeds from that DFT to determine the adjustable filtering weights of the ghost cancellation filter. The computer thereafter responds to the separated PN sequences to determine the adjustable filtering weights of the equalization filter.

摘要： A method and apparatus for encoding/decoding data, wherein for one embodiment, during [During] encoding, a microprocessor (201) calculates Ym by standard Reed-Solomon encoding techniques. The microprocessor (201) then utilizes Ym as an index to a look-up table (203), and is returned G0Ym, G1Ym, . . . , GK−1Ym, from the look-up table (203). During syndrome calculation, a second set of parity symbols are generated from the information symbols using the method similar to the encoder, in particular, values for G0Ym, . . . , GK-,Y. are obtained from a first look-up table (503) in a similar manner as encoder to determine the values for G0Ym, G1Ym, . . . , GK−1Ym. A second look-up table (505) is set up to determine roots of the error locator polynomial. The second look-up table consists of several tables and each table contains (Q−1) elements, where Q is the size of the GF(Q) field. The mth look-up table stores Galois Field element &agr;−mi at location i if the greatest common denominator between (Q−1) and m (GCD(Q−1,m))=1. If GCD(Q−1,m)≠1, then the mth look-up table actually consists of (GCD(Q−1,m) sub-tables storing GF element &agr;−(mi=i), where j=0, 1, . . ., GCD(Q−1,m)−1.

摘要： The present invention provides new methods, employing a nucleotide integrase, for cleaving double-stranded and single stranded DNA substrates at specific sites and for attaching nucleic acid molecules to the cleaved DNA substrates. One method uses a nucleotide integrase to cleave one strand of a double-stranded DNA and to concomitantly attach a nucleic acid molecule to the cleaved strand. Another method uses a nucleotide integrase to cleave both strands of a double-stranded DNA substrate and to attach a nucleic acid molecule to one strand of the DNA substrate. Another method uses a nucleotide integrase to cleave both strands of a double-stranded DNA substrate and to attach an RNA molecule to one strand of the substrate and for attaching a cDNA to the other strand of the substrate. Another method cleaves single stranded DNA with the concomitant insertion of a nucleic acid molecule at the cleavage point. The nucleotide integrase comprises an RNP particle which comprises a group II intron RNA bound to a group II intron encoded protein. The present invention also relates to purified and reconstituted RNP particles and reconstituted RNP that cleave DNA substrates.

摘要： A ghost-canceling reference signal for inclusion in a television signal is provided by cyclically inserting ones of extended-length complementary-sequence pairs into a prescribed scan line in each of the vertical blanking intervals of successive fields of the television signal. By definition, a pair of binary (.+-.1) sequences of similar length to each other are complementary sequences only if the sum of the linear autocorrelation functions of the sequences is identically zero for all shifts other than zero but provides a high correlation gain at zero shift. A television receiver is described for receiving television signals containing such ghost-canceling reference signals, separating the ghosted complementary-sequence pairs from the received television signals, linearly correlating the ghosted complementary-sequences with corresponding ghost-free complementary-sequences previously stored in the receiver, and adjusting the filtering parameters of ghost-canceling video filters in accordance with the sum of the linear correlation results.
