Abstract :
We present a novel infrared communication system for large cells and low user mobility. The proposed transmitter technique allows nearly perfect direction-of-arrival (DOA) estimation in time division multiple access (TDMA) environments only with three photodiodes. Using a photodiode array we show that known algorithms for DOA-estimation can be applied in spatial division multiple access (SDMA) systems
