In this paper, the authors study the effect of PHase Noise (PHN) in a Single Carrier Cyclic Prefix (SCCP) system operating with a known cyclic prefix. The PHN process is a limiting factor in high throughput communication systems as higherorder constellations are extremely sensitive to it. In this paper, the authors propose a robust and non-iterative scheme to enhance both the estimation of, and compensation for, the PHN process and this also includes channel estimation. In contrast to existing approaches for PHN compensation, in this paper they use a known cyclic prefix, pilot bins and interpolation over the PHN estimates.
