A novel design of context aware based on equalizer in cognitive networks

Cognitive networks use context aware as its basic approach to realize intelligent decision-making and network reconfiguration, thus, context aware becomes a worthy researching field. However, the current existing context aware schemes are almost general and indistinct. In this paper, a novel practical design of context aware based on DEF variable length equalizer (VLE) is proposed. By perceiving the relationship between time-delay and tap-length of the equalizer, we can get to know the communication environment approximately. This idea is applicable to solve the near-far problem and power management in CDMA and WCDMA, and it is also useful in the research of access select in the future heterogeneous networks.
