A Novel 2D ASCO-OFDM Scheme In Wireless Communication
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2016, Vol 3, Issue 3
Abstract
The asymmetrically and symmetrically clipping optical OFDM (ASCO-OFDM) in two dimensional (2D) intensity modulation direct detection (IM/DD) is a novel technique in optical wireless communication (OWC). In 2D ASCO-OFDM the asymmetrically clipping optical OFDM (ACO-OFDM) symbols and the symmetrically clipping optical (SCO)-OFDM symbols are mapped into odd columns of transmitted matrices respectively. The spectral efficiency of 2D ASCO-OFDM is twice as much as that of 2D ACOOFDM and other conventional OFDM. Comparing with different constellation, 2D ASCO-OFDM reduces the Peak-to-Average power ratio (PAPR) by 2dB. Moreover the SER performance of 2D ASCO have high bit rate, and it exhibit better performance
