N2 - In this letter, we experimentally demonstrate the discrete multitone (DMT) modulation scheme for organic light emitting diode-based visible light communications (OLED-VLC). DMT is based upon quadrature modulation of orthogonally spaced frequencies, meaning the scheme is extremely spectrally efficient. With this technique, we set a new world record data rate of 1.4 Mb/s, which is far in excess of the previous record of 550 kb/s. We achieve this using a 32-level quadrature amplitude modulation (32-QAM) in conjunction with 1024 subcarriers. We show that it is possible to recover signals up to 1.4 Mb/s with an OLED of bandwidth less than 100 kHz, which is an increase of over 14 times.
