Abstract
We experimentally investigate the effect of pilot power allocation on the performance of baseband direct-detected optical orthogonal frequency division multiplexing system by comparing five pilot power allocation schemes. The results show that the scheme of increased pilot power allocation had the highest receiver sensitivity and frequency fading tolerance of all. Allocating more power on pilots at higher frequencies can improve the accuracy of channel estimation which leads to a better system performance.
