Channel selection exploiting multiple observations of the channel delay spread

摘要

A method, a mobile system, and a user device for determining a delay spread are disclosed. A memory 306 may store a compound test value based on a multiburst history. The multiburst history may be a set of power delay profile decisions. A processor 304 may create a short power delay profile channel estimate and a long power delay profile channel estimate. The processor 304 may select a chosen power delay profile channel estimate based on the compound test value.

1. A method for determining delay spread, comprising:
storing a compound test value based on a historical multiburst set of power delay profile decisions; receiving a new transmission burst; creating a short power delay profile channel estimate and a long power delay profile channel estimate for the new transmission burst, wherein a delay spread of the long power delay profile channel estimate is larger than a delay spread of the short power delay profile channel estimate; combining each of the short power delay profile channel estimate and the long power delay profile channel estimate with the compound test value based on the historical multiburst for forming a new updated compound test value; and selecting a chosen power delay profile channel estimate from the short power delay profile channel estimate and the long power delay profile channel estimate, based on the new updated compound test value.
