The mean square error (MSE) of the channel estimation algorithm, the bit error rate (BER) and the Cramer-Rao (CR) lower-bound of the system were obtained analytically and the performance of the algorithm according to the signal-to-noise ratio was investigated by computer simulations. From the obtained MSE, BER and CR curves it is concluded that the MSE performance of the proposed channel estimation algorithm is very high and the BER performance of the system obtained with the estimated channel information is very close to the BER performance in the case of perfect knowledge of the channel.trinfo:eu-repo/semantics/closedAccessVisible light communication(VLC)orthogonal frequency division multiplexing(OFDM)generalized LED index modulation(GLIM-OFDM)channel estimationConference ObjectWOS:00080810070028310.1109/SIU53274.2021.94780422-s2.0-85111451862N/AN/A
