Nowadays, Radio Frequency (RF) bands in wireless communication have been rapidly filled and reached the upper limits of the frequency band due to the high data rate and developing technologies.This situation increases the interest on new alternative communication technologies.Hence, the VLC (Visible Light catherine lansfield ombre rainbow clouds eyelet curtains Communication) comes into play to mitigate data traffic over RF for short distances.

The design of modulator and demodulator design in VLC is one of the most important issues because it affects features such as error performance, bandwidth efficiency, power efficiency.Therefore, the performance analysis of DPIM (Digital Pulse Interval Modulation) technique used for VLC systems was performed in this paper.The analyzes were carried out in MATLAB environment.

In the study, error correction codes are integrated into DPIM technique.By achieving the mathematical infrastructure of the integrated error correction codes, a comparison of the conventional system with SER (Slot Error Ratio) and PER (Packet Error Ratio) was obtained in the simulation.The proposed receiver structure has been shown aluminum lotion to perform better than traditional DPIM receiver structure.

Therefore, it can be seen from the simulation results that the error correction codes can be transmitted to the traditional structure for higher tranmission distance.Especially, it is seen that the error correction structure considerably improves the error performance for constant threshold value application.
