一种基于LED通信的调制方案
A modulation scheme based on LED communication
摘要
Abstract
In order to meet the requirement of high frequency band utilization and low SNR in LED communication,a new modulation scheme called n-dimensional multilevel stage modulation (nD-MPAPM)is proposed,which is combined with multidimensional modulation and pulse amplitude modulation.Information transfer rate,frequency band utilization,power requirements and bit error rate are analyzed.Simulation results show that nD-MPAPM has the highest bandwidth efficiency and its information transfer rate is n times than MPPM,M-PPM and MPAM.SNR of 4D-2PAPM has 3 dB improvement than 4-PPM and 2.6 dB improvement than 2D-4PAPM when bit error rate is 10-3 .关键词
