Fuzzy-Neural Applications in Handoff

Handoff is a process of transferring a mobile station from one base station or channel, to another. The channel change due to handoff occurs through a change in a time slot, frequency band, codeword, or a combination of these, for time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDMA), or a hybrid scheme, respectively. The handoff process determines the spectral efficiency (i.e., the maximum number of calls that can be served in a given area) and the quality perceived by users. Efficient handoff algorithms cost-effectively preserve and enhance the capacity and Quality of Service (QoS) of communication systems.
