چکیده

This paper presents a comparative study of the performance of commonly used modulation techniques for Indoor Optical Wireless Communications. Some commonly used modulation schemes such as OOK, PPM, PIM and MSM are discussed and their properties are compared with respect to their power and bandwidth requirements. Their relative merits and demerits are also highlighted. The results were computed using MATLAB.
