PAPR Reduction of Optical OFDM Systems with Exponential Companding Transform and Zero Padding

Creator:: Chen, Deyan
Abstract:: Optical wireless communication (OWC) is an alternative to radio frequency (RF)communication with a signi cantly larger and unregulated spectrum. In OWC systems, optical orthogonal frequency division multiplexing (O-OFDM) with intensity modulation and direct detection (IM/DD) is commonly used. There are two common signal structures in most OWC systems based on...

Threshold Selection Based on the SNR in Time of Arrival Localization System

Creator:: Lyu, Tao
Abstract:: Threshold-based time of arrival (TOA) estimation is a technique for high-precision indoor localization. Existing threshold selection methods, such as xed thresh- old and normalized threshold methods, do not consider the signal-to-noise radio (SNR) value at the receiver. This is not desired for high-precision positioning. A proper threshold value depends on...
