Hi Damian,
50Hz is the powerline frequency of the fluorescent lamp used in indoor environment.
I need to model the channel as awgn channel.This ambient light noise will cause shot noise at the rx and i also need to include thermal noise.
Should i need to include white noise source in channel addition to LED and again in need to include photodiode diode parameters for shotnoise and thermal noise.If so how the optical filtering can be done here.How should i realise the channel here.
Please kindly help on this regards Damian.
