Abstract :
A new and simple receiver structure for reducing the multipath inter-symbol interference (ISI) effect is proposed for infrared diffuse links. In this new method, bit-error rate (BER) performance of the system will be improved significantly without any essential change in the receiver structure. In our analysis, all major noise sources such as ambient light, signal shot noise, dark current and thermal noise of the receiver are considered.
