Channel Characteristic and Transmission Performance of An Indoor Wireless Optical Communication System

Channel characteristics of an indoor wireless optical communication system is provided here. A channel impulse response includes the power ratio and time delay due to bounce times. Based on the scenario of the indoor structure, we obtained and discussed the received power distribution according to six configurations in Table 1, which vary with respect to transmitter and receiver positions and reflection coefficients. We used the input Gaussian pulse, Rectangular pulse, and Practical pulse, which are applied to pulse position modulation (PPM) and OOK, based on the impulse response of indoor channels in Configuration D. We evluated the BER with respect to the signal-to-noise ratio per bit for various input pulses in lineof-sight (LOS) and diffuse channels.
