Abstract :nverse pulse position modulation is one of the modulation techniques for Visible Light Communication VLC systems. In this paper, a new demodulator scheme, which is named as Slot Period Detector SPD , is proposed by using frequency detection technique. The proposed architecture computes the period time for each slot. Thanks to SPD technique, the complexity of I-PPM receiver is dramatically reduced. However, the traditional receiver has better Bit Error Rate BER performance than that of proposed SPD structure. The important issue is that whether the proposed receiver is practicable for real-time systems hence, the SPD is implemented on Field Programmable Gate Arrays FPGA board to demonstrate an applicable receiver.
