Abstract: A method for generating and outputting a message is implemented using an electronic device the stores a computer program product and a text database. The text database includes a main message template, a template text that includes a placeholder, and a word group that includes a plurality of preset words for replacing the placeholder. The method includes: in response to receipt of a command for execution of the computer program product, displaying an editing interface including the main message template; in response to receipt of user operation of a selection of the main message template, displaying the template text; in response to receipt of user operation of a selection of one of the preset words via the user interface, generating an edited text by replacing the placeholder with the one of the preset words in the template text; and outputting the edited text as a message.

Abstract: A sorted QR decomposition method used in a detection of a multiple input multiple output (MIMO) communication system is provided. First, whether a sorting-stop parameter of a channel transformation matrix of the MIMO communication system is greater than or equal to a sorting-stop threshold is determined. Then, whether energy of elements in a leftmost column within a process area of the channel transformation matrix is completely transferred to a top element in the leftmost column is determined. If the energy of the elements in the leftmost column within the process area is not yet completely transferred to the top element in the leftmost column, a unit process area of a process unit set is expanded.
