Method and system for effecting handoff in a cellular communication system
TLDR
In this article, a method and system for handing off an on-going communication from a serving cell to a neighboring cell of a cellular communication system having scanning receivers associated with each base transceiver station is presented.Abstract:
A method and system for handing off an on-going communication from a serving cell to a neighboring cell of a cellular communication system having scanning receivers associated with each base transceiver station. A dynamic threshold is calculated for effecting the handoff in accordance with various operating conditions. The current mobile minimum attentuation level, (MT) the minimum permissible attenuation level of a serving (MS) cell and a neighboring cell (MN), together with the RF signal strength of the mobile unit at the neighboring cell (RSSI-NBR) and the serving cell (RSSI-SRV) are used in calculating a dynamic threshold (RSSI-THP).read more

Digital code reading apparatus and method
TL;DR: In this paper, a digital code reader reads the digital key code in a scrambled video signal and uses a threshold signal to reproduce the key code from the received signal by comparison of the levels of the received signals with the level of the threshold signal.
