There is types of frame structure in the LTE standard, type 1 and type 2. Type 1 uses Frequency Division duplexing (Uplink and downlink separated by Frequency), and TDD uses time division Duplexin G (Uplink and downlink separated in time). This overview covers both LTE FDD Type 1 signals and LTE TDD type 2 signals described in the standard documents listed in The About Opts BHD and bhe:lte modulation analysis topic. This overview isn't a exhaustive description of the physical layer, but is inten

This article mainly introduces two ways to compress ASPX pages to remove extra space, you can compress aspx before publishing the page, without wasting the CPU on the Web server, you need friends to refer to the following Two ways to implement:nbsp; 1 read ASPX files on one line and then process nbsp; 2 read the ASPX file once and then handle nbsp; processing logic:nbsp; Replace "nbsp;" as "" (replace two spaces with one space), Replace all line breaks with empty characters (limit compression)
