This paper proposed the Modulation and Coding Selection (MCS) scheme according to the received angle in LED-ID optical wireless system. If location of LED-ID receiver is different, the optical power of received signal is different due to the received angle in LED-ID system. Therefore, system performance varies as the receiving angle changes, affecting the stability of the whole system. In the implemented LED-ID transceiver with 400Mbps data rate, a combination of convolutional code and variety modulation order such as BPSK, QPSK, 16QAM, 64QAM is adaptively changed based on the received power according to received angle in the LED-ID channel. The proposed system can achieve improved throughput in comparison to those of conventional LED-ID systems, as well as a superior target bit error rate (BER).
