C Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2011 Design and Evaluation of a Fall Detection Algorithm 29 of current technologies. Reliable fall detection and notiﬁcation is essential in independent living facilities and in ambulatory systems for elders or patients. The objective is to improve the medical outcome which is largely dependent upon the response and rescue time. Immediate reporting to caregivers after fall event detection can certainly improve the health outcome due to faster caregiver response and appropriate medical care.
2 The FDD MIMO LTE Simulation Model This section presents the simulation setup environment. The simulation results ware obtained with the Agilent Advanced Design System (ADS) . T. K. Chronopoulos downlink MIMO 4x2 coded measurements on fading channels for all the combinations of the parameters discussed bellow. Figure 1 shows a schematic diagram of the simulation model that consists in three main blocks: transmitter, channel and receiver chains. Fig. 1. The FDD MIMO LTE simulation model Table 1.
