Abstract: Provided is method for generating a precoder in a Multi User Multiple Input and Multiple Output (MU MIMO) communication system. The method involves receiving channel information and quality information of a channel from a plurality of stations. It is determined whether a first condition is satisfied on the basis of the received information, if so, a type of matrix inversion is selected from among a plurality of matrix inversion types for precoding. It is determined whether a second condition is satisfied on the basis of the provided information, and a type of decomposition from a plurality of decomposition types for precoding is selected if the second condition is satisfied. A precoder is generated on the basis of the selected result.

Abstract: A semiconductor device includes a substrate, a first fin, and a second fin. The first and second fins are spaced apart from each other in a first direction on the substrate and extend in a second direction intersecting the first direction. The semiconductor device further includes a first shallow trench formed between the first and second fins, and a field insulating film which fills at least a part of the first shallow trench. The field insulating film includes a first portion, a second portion adjacent to the first portion, and a third portion adjacent to the second portion and adjacent to a side wall of the first shallow trench. The first portion includes a central portion of an upper surface of the field insulating film in the first direction. The upper surface of the field insulating film is in a shape of a brace recessed toward the substrate.

Abstract: A semiconductor device includes first and second active patterns on a substrate, the first and second active patterns adjacent to each other in a first direction with a first trench between the first and second active patterns, third and fourth active patterns on the substrate, the third and fourth active patterns adjacent to each other in the first direction with a second trench between the third and fourth active patterns. The semiconductor device includes a first device isolation layer in the first trench, and a second device isolation layer in the second trench. A width of the second trench in the first direction is greater than a width of the first trench in the first direction. The second device isolation layer includes a first protrusion and a second protrusion which protrude from a top surface of the second device isolation layer.
