Expanded Multiband Super-Nyquist CAP Modulation for Highly Bandlimited Organic Visible Light Communications

Popis výsledku v původním jazyce

In this article, we experimentally demonstrate a novel expanded nonorthogonal multiband super-Nyquist carrier-less amplitude and phase ( m -ESCAP) modulation for bandlimited organic visible light communication (VLC) systems. The proposed scheme has the same bandwidth requirement as the conventional m -CAP while breaking the orthogonality between subcarriers by purposely overlapping them. We compare m -ESCAP with the conventional m -CAP and a compressed nonorthogonal version of m -CAP ( m -SCAP) in terms of measured bit error rate (BER) performance, bit rates, and spectral efficiencies. We show that the m -ESCAP system offers improvement in the bit rate of ~ 10% and 20% compared to the m -CAP and m -SCAP, respectively, and in the spectral efficiency of ~ 20% compared to m -CAP. These gains are achieved at the cost of increased BER, which, however, remains below the 7% forward error correction limit.
