The Improved Precoding Method in the VLC-Based Intelligent Transportation System

چکیده
Visible light communication (VLC) transmission system, combined with lighting and communication, has a great application value in the field of intelligent transportation. To efficiently improve performance VLC-based transportation an improved precoding scheme is proposed experimentally verified. Partial data-carrying subcarrier (PDS)-precoding can balance signal-to-noise ratio (SNR) combat frequency selective fading (FSF) system. For ?3.52 Gb/s DMT-VLC system 1.9-m free space transmission, OCT-based PDS-precoding signal shows almost same BER as full subcarriers ones. Compared conventional scheme, reduced from 2e-3 to 8.14e-5 by using PDS-precoding. nice choice degrade unbalanced damage for (SCs) bandwidth-limited
