Most current development strategies for future mobile systems are concerned with partial solutions only regarding the mobility-bit rate problem. In this paper the basic ideas of the Integrated Broadband Mobile System (IBMS), supporting in a unified way a variety of communication classes ranging from high mobility with low data rates towards(More)
In this paper we present a n o v el 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 w e show that known algorithms for DoA-estimation(More)
