摘要： An apparatus and method estimates the adaptive wireless channel for a moving vehicle. Once a packet is received, this invention analyzes a channel interference index for the moving vehicle, and computes a first recursive parameter, a second recursive parameter and an interpolation number. Based on the first recursive parameter and the interpolation number, partial channel information is calculated for further channel estimation by using an interpolation. The parameter of an equalizer is also immediately updated. Cooperating with a decision feedback scheme and based on the second recursive parameter, channel tracking is performed. In order to achieve the adaptive channel estimation for wireless access on the time-variant vehicle environment, the parameter for the algorithm for performing the channel estimation is adjusted.

摘要： An adaptive handover method in a heterogeneous network environment collects estimation information for a channel environment and integrates with a wireless device's geographic information to decide two groups of recursive parameters and a channel theoretical signal model. The model and the first group of recursive parameters are used to execute recursive iteration for a signal strength decay theoretical value. The obtained actual signal strength decay value from channel estimation, the second group of recursive parameters and the signal strength decay estimation value at previous iteration are used to execute channel-tracking recursive iteration for obtaining a signal strength decay tracking value. The current network status and the signal strength decay tracking value are used to predict and analyze system performance of heterogeneous networks. A decision is made based on each heterogeneous network's analyzed result, and an adaptive handover procedure is prepared by following the decision.

摘要： Disclosed relates to an adaptive handover method in a heterogeneous network environment. Once a wireless device starts up, the invention collects estimation information for a channel environment and integrates with the wireless device's geographic information to decide two groups of recursive parameters and a channel theoretical signal model. The model and the first group of recursive parameters are used to execute recursive iteration for a signal strength decay theoretical value. The obtained actual signal strength decay value from channel estimation, second group of recursive parameters and the signal strength decay estimation value at previous iteration are used to execute channel-tracking recursive iteration for obtaining a signal strength decay tracking value. The current network status and the signal strength decay tracking value are used to predict and analyze system performance of heterogeneous networks. Based on the analyzed result, prediction time is also regulated. A decision is made based on each heterogeneous network's analyzed result, and an adaptive handover procedure is prepared by following the decision.
