LI Hong, YANG Chao. OFDM Modulation with Signal Space Diversity for Indoor Visible Light Communications[J]. 2016,(3):62-64. DOI: 10.13756/j.gtxyj.2016.03.020.
The communication rate and reliability is greatly affected by the channel fading effect.In order to solve the problem
we propose a method based on Signal Space Diversity(SSD)in OFDM modulation scheme in this paper.The experimental results show that the method can achieve 0.7
1
.3dB Bit Error Rate(BER)improvement at the data rate of 120
1
60Mbit/s in fading environment with over 9
2
4dB attenuation in Visible Light Communication(VLC)system.
