Demodulation of PDSM Signal by Using Multiple Sampling Technique
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2017, Vol 5, Issue 4
Abstract
The design of modulator and demodulator for wireless optical communication systems is one of the important issues. In this paper, a new receiver scheme is proposed for PDSM (Pulse Dual Slope Modulation) architecture which is used for VLC (Visible Light Communication). It is shown that the scheme that is referred as multiple sampling technique based demodulator architecture in this paper has lower BER (Bit Error Rate) than that of the traditional dual sampling demodulator architecture. However, the proposed demodulator has lower bit error rate performance compared with the traditional PDSM receiver scheme. The proposed receiver is designed on FPGA (Field Programmale Gate Arrays) complier. According to FPGA complier’s simulation results, it is shown that the receiver succesfully estimates data bits.
