Location management in cellular mobile radio networks
− Location Management is the procedure of keeping track of and locating Mobile Terminals (MT’s) in mobile radio communication system so that calls arriving for them can be routed correctly to their current location. The main aim of the Location Management is to track the MT’s using minimum overhead traffic. Since the radio bandwidth is a scarce resource in mobile radio communication systems, it...
متن کاملApplication of Per-Survivor Processing for Digital Mobile Radio
The bandwidth efficient modulation format OQPSK is implemented up to now merely in mobile radio systems which do employ spread spectrum techniques, i.e. it is not used in narrow band systems. This is due to the fact, that, in spite of its reduced performance degradation in non-linear channels in comparison to other linear modulation formats, for OQPSK no receivers were derived up to now, which ...
متن کاملChannel quality estimation and rate adaptation for cellular mobile radio
We propose a technique to measure channel quality in terms of signal-to-interference plus noise ratio (SINR) for the transmission of signals over fading channels. The Euclidean distance (ED) metric, associated with the decoded information sequence or a suitable modification thereof, is used as a channel quality measure. Simulations show that the filtered or averaged metric is a reliable channel...
متن کاملUsing LDA Method to Provide Mobile Location Estimation Services within a Cellular Radio Network
Mobile location estimation is becoming an important value-added service for a mobile phone operator. It is well-known that GPS can provide an accurate location estimation. But it is also a known fact that GPS does not perform well in urban areas like downtown New York and cities like Hong Kong. Then many mobile location estimation approaches based on the cellular radio networks have been propos...
متن کاملDecentralized Slot Synchronization for Cellular Mobile Radio
*1 IMT-Advanced: A standard positioned as the successor to IMT-2000 at International Telecommunication Union Radiocommunication sector (ITU-R). It calls for data rates of about 100 Mbit/s for high mobility and 1 Gbit/s for low mobility. *2 ad hoc network: A network in which several mobile terminals communicate without any dedicated infrastructures such as base stations or access points. *3 UWB:...
