What it is: A while loop runs a block of code repeatedly as long as a specified condition is true, checking the condition before each iteration. Why it matters: It’s ideal for tasks with unpredictable ...

Abstract: This paper presents a new infinite phase shifter using current-output digital-to-analog converters (DACs) with tapped load resistors. The linear phase control characteristic can be achieved ...

Abstract: Physical layer security key generation exploits unpredictable features from wireless channels to achieve high security, which requires high reciprocity in order to set up symmetric keys ...
