3D mask face presentation attack detection (PAD) plays a vital role in securing face recognition systems from emergent 3D mask attacks. Recently, […]

A review of hybrid couplers

In recent years, the hybrid branch-line coupler has attracted much attention due to its appealing features such as of low cost and […]

Energy Detection for M-QAM Signals

In this paper, we address energy detection for M-ary quadrature amplitude modulation (QAM) signals. In the literature deterministic signal model is widely […]

Permutation Channel Modulation

In this paper, we propose a novel index modulation mechanism called permutation channel modulation (PCM) by exploiting spatial resource of multiple input […]
