Title: Combined 64-qam and 256-qam tcm decoder
Inventor: JEGAL HEON
IPC: H03M7/00
Filed: 1998-12-28
Abstract: PURPOSE: A combined 64-QAM and 256-QAM TCM decoder is provided to decode both a 64-QAM signal and a 256-QAM signal. CONSTITUTION: A combined 64-QAM and 256-QAM TCM decoder comprises a control part(110) which detects whether an input bit stream is 64-QAM or 256-QAM and generates either a 64-QAM decoding command signal or a 256-QAM decoding command signal according to the detection result. An uncoded bit memory(120) stores ones not coded in the input 64-QAM or 256-QAM codes in response to the 64-QAM decoding command signal and the 256-QAM decoding command signal. A de-puncturing block(130) de-punches the input 64-QAM or 256-QAM codes. A branch matrix(140) is operated responsive to the 64-QAM decoding command signal and the 256-QAM decoding command signal, and generates a 64-QAM branch matrix or a 256-QAM branch matrix according to the de-punctured codes. An ACS part(150) adds the 64-QAM or 256-QAM branch matrix from the branch matrix to a previously stored pass matrix, and compares the added values to select an optimum path. A survival memory(160) searches an optimum path by a trace algorithm, and then detects a maximum possible symbol. A differential pre-coder(170) differentiates and pre-codes the maximum possible symbol. An uncoded bit de-mapper(180) is operated responsive to the 64-QAM decoding command signal and the 256-QAM decoding command signal, and de-maps uncodes from the memory(120). A data parser(190) parses the uncodes from the de-mapper(180) and the differentiated pre codes, and outputs decoded codes as the result.

Abstract: A construction system where elements have connection components for a ball-to-socket or socket-to-socket connection. The ball-to-socket connection "locks" at orientations when one or more detents in the interior of the socket protrude into one or more of a plurality of dimples on the ball. The construction elements generally have an elongated body with a dimpled ball at one end and a socket at the other end, or dimpled balls at both ends, or sockets at both ends. In addition to the ball-and-socket connection, elements may connect in a socket-to-body connection, or a number of different types of socket-to-socket connections. The socket has at least two petals with a lip contour such that in one type of socket-to-socket connection the pair of sockets interlock to form a sphere. The irregular shape of the lip of the socket allows a ball to be leveraged out of a socket, and make orientations over at least 2 pi  steradians available in a ball-to-socket interconnection.

Abstract: PURPOSE: Provided is a phosphate resin-based coating composition for forming an insulated coating of a non-oriented electrical steel sheet, which can improve appearance and insulation property after annealing for eliminating stress. CONSTITUTION: The coating composition is produced by adding(based on phosphoric acid of 100 g in aluminium phosphate solution) 40.2-102.5g(based on solid state) of an acid soluble emulsion type acryl-styrene copolymer resin, 9.3-19.7g of zinc nitride, 3.2-15.8g of talc, and 0.6-12.4g(based on solid state) of acidic colloidal silica and also adding(based on the emulsion type acryl-stylene copolymer resin of 100g based on solid state) 2.2-21.5g of a crosslinked resin additive and 14.2-77.2g of ethylene glycol in the aluminium phosphate solution and then adjusting concentration with water. The insulated coating is produced by coating the surface of the non-oriented electrical steel sheet with the coating composition and then annealing at 550-750 °C for 14-45 minutes.
