摘要:
In a VSB system, a method for channel modeling to estimate coefficients corresponding to a selected subspace is provided. The method comprises the steps of: selected a predetermined subspace; creating a set of bi-orthogonal vectors for the initially selected subspace; and obtaining a set of coefficients by solving a linear programming problem. Whereby the resultant channel is constructed by the coefficients and their associated subspace.

A method of wet etching semiconductor zinc tin oxide includes submerging a semiconductor zinc tin oxide film in a bath solution. The film is partially covered with a pattern of protective material, and the bath solution etches semiconductor zinc tin oxide film not covered by the protective material. A system for wet etching semiconductor zinc tin oxide includes a bath containing a bath solution. The bath solution is effective to wet etch the semiconductor zinc tin oxide.

A method for making a silicone hydrogel contact lens is provided. In one embodiment, a prepolymer mixture is polymerized in a lens mold in an atmosphere having less than about ppm oxygen to form a silicone hydrogel contact lens suitable for extended wear as characterized by producing less than 10% corneal swelling after a period of continuous wear of 7 days including normal sleep periods. In one embodiment, the prepolymer mixture comprises at least one oxyperm material containing hydrophilic groups, wherein the at least one oxyperm material is a siloxane-containing macromer or monomer, at least one ionperm material, and a cross-linking agent. In certain embodiments, the polymerization of the prepolymer mixture may be carried out in an atmosphere having less than about 1000 ppm oxygen.

摘要:
In an OFDM system, a method for interpolating comprising the steps of: subdividing at least one frame among a plurality of frames into segments; and using at least two known quantities to interpolate a corresponding estimate.
摘要:
A method for channel equalization is provided. The method comprises the steps of: subdividing a received symbol portion into segments wherein each segment is associated with a known, segmented channel characteristic among a set of segmented, known channel characteristics spanning the received symbol.
摘要:
In frequency equalization, a received signals goes through frequency transform, the transformed signal is divided by a frequency transform of a channel response a method for equalization. The method comprises the step of: adjusting a quotient of the division by a weight function, wherein the function varies under a set of conditions; whereby for a frequency selective channel, deep fades are adjusted, and noise or interference are reduced.
