Low Density Parity Check (LDPC) codes can be decoded in various ways, namely the Bit-Flipping (BF) algorithm, the Weighted BF algorithm (WBF), the Belief Propagation (BP) algorithm and so on. These algorithms provide a wide range of tradeoffs among decoding complexity, decoding speed, and error rate performance. In this paper, a novel self-reliability-based weighted bit-flipping decoding scheme...

This paper presents NORX8 and NORX16, the 8-bit and 16-bit versions of the authenticated cipher NORX, one of the CAESAR candidates. These new versions are better suited for low-end systems—such as “internet of things” devices—than the original 32-bit and 64-bit versions: whereas 32-bit NORX requires 64 bytes of RAM or cache memory, NORX8 and NORX16 require just 16 and 32 bytes, respectively. Bo...

Fixed low-resolution Analog to Digital Converters (ADC) help reduce the power consumption in millimeter-wave Massive Multiple-Input Multiple-Output (Ma-MIMO) receivers operating at large bandwidths. However, they do not guarantee optimal Energy Efficiency (EE). It has been shown that adopting variable-resolution (VR) ADCs Ma-MIMO can improve performance with Mean Squared Error (MSE) and through...
