This paper studies cooperative user positioning using uplink time-difference-of-arrival (UTDOA) measurements for 4G Long Term Evolution (LTE) cellular networks. Many applications in a cellular network, such as location-based services and E-911, rely on accurate locations of users in the network. Although the Global Positioning System (GPS) is widely used in cellphones, their poor localization performance...
In this paper, cooperative positioning for Long Term Evolution (LTE) cellular systems using Radio Frequency Pattern Matching (RFPM) is studied. Having the locations of users in a cellular system supports many applications such as location-based services and E911. Although Global Positioning System (GPS) can be found in every smartphone, its poor performance in indoor and dense environments encourages...
This paper represents a preliminary study of cooperative positioning in Long Term Evolution (LTE) systems. Many applications, such as location-based services and Enhanced 911 (E911), require that the locations of users in a cellular system are available. The global navigation satellite system (GNSS) is the most accessible positioning systems which are widely used in cellphones. However, poor operation...
