Abstract:
A method to adapt a set of multi-point channel estimation filters for use in wireless communications including measuring a plurality of reception values is provided. Each reception value included in the plurality of reception values is associated with one of the network nodes. The method includes sorting the plurality of reception values according to magnitude and determining a select reception value. The method includes selecting a particular network node from the set of network nodes based on the reception value. The reception value is within a threshold from the select reception value. The method includes adjusting the length of a multi-point channel estimation filter associated with the particular network node. The adjusting the length is based on a lookup table and on the reception value associated with the particular network node, according to some embodiments. User equipment in a wireless network adapted for the above method is also provided.
