Samenvatting
A new inter-frame polar coded modulation scheme is proposed and experimentally demonstrated in an infrared light communication (ILC) system. The scheme utilizes the Monte Carlo (MC) method to jointly design an inter-frame polar code with 16-ary quadrature-amplitude modulation (16QAM) and orthogonal frequency-division multiplexing (OFDM). The indoor transmission of 9.6 Gbit/s 16QAM OFDM signal is experimentally achieved over a 3.2 km single-mode fiber and 0.8 m free space. The experiment results show that the proposed scheme employing a polar code of length 1024 and cyclic redundancy check aided successive cancellation list (CA-SCL) decoding with a list size of 2 resulted in no errors over 107 bits. Moreover, the proposed scheme requires negligible extra decoding complexity with respect to its classical counterpart, MC-constructed polar coded modulation. To the best of our knowledge, this is the first experimental demonstration of a polar coded modulation based infrared light communication system.
