Channel Capacity and BER Estimation of Indoor Optical Wireless Communication System under Receiver Mobility

The existing radio frequency technologies face the bandwidth limitation due to the increase in the number of devices being used inside the indoor environment. though, the backbone networks are capable of carrying a large amount of data to the tune of several hundreds of gigabits per second, the last mile techniques, especially the indoor connectivity, continue to pose a challenge in terms of handling large data capacity. The indoor optical wireless communication could be one such promising technology that is potentially capable of handling large amount of data transmission within the indoor environment. The receiver mobility may largely affect the key communication parameters which undergo spatial variations. Therefore, in this paper, we investigate several parameters especially the channel capacity, bit error rate, received pulse power, pulse delay spread and signal-to-noise ratio pertaining to receiver mobility. © 2018 Walter de Gruyter GmbH, Berlin/Boston 2018.
