KeeLoq is a lightweight block cipher with a 32-bit block size and a 64-bit key. Despite its short key size, it is used in remote keyless entry systems and other wireless authentication applications. For example, there are indications that authentication protocols based on KeeLoq are used, or were used by various car manufacturers in anti-theft mechanisms.(More)
This paper presents an all-digital signal component separator (SCS) with low power overhead for uneven multilevel LINC (UMLINC) systems, including a multi-level phase calculator (MLPC) and a digitally-control phase shifter (DCPS) pair. The optimal gain level with branch mismatch consideration is proposed to achieve maximal average efficiency 44.82%. This(More)
