Mobile assisted handoff based on Euclidean distance metric
Ruifeng Zhao, Hailin Jiang, Zhenhui Tan · 2002
It is important for mobile assisted handoff (MAHO) to accurately measure channel quality and report it to the serving base station, which can help to avoid unnecessary handoffs and reduce handoff delay. We use 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, is used as a channel quality measure. Simulations show that the averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes and at different mobile speeds. The ED metric works well for MAHO, reducing unnecessary handoffs and handoff delay.
