Performance improvement for a WCDMA radio over fiber system using digital pre-distorter

  • Published:
Journal of Electronics (China)

Abstract

In this paper, a Radio Over Fiber (ROF) system with a Digital Pre-Distorter (DPD) for WCDMA signal transmission is investigated. A Look-Up Table (LUT) based DPD and a Memory Polynomial (MP) DPD are applied in the ROF link so as to suppress the out-of-band spurious spectrum and improve the transmission performance. The experimental results show that the out-of-band emission due to existence of the third-order Inter-Modulation Distortion (IMD3) is obviously suppressed by these two DPD. An Adjacent Channel Power Ratio (ACPR) improvement of 8 dB is obtained for a single-carrier WCDMA signal transmission. These two DPD have equal ability in linearization of the ROF system for a three-carrier WCDMA signal transmission. There is no apparent memory effects exist in the ROF link.
