Unified interference power estimation

摘要

A communication device, such as a smart phone, includes logic to determine a noise power estimate. In an example, a frequency domain calculation may be used to determine noise components within the noise power estimate. Further, a product of a channel estimate and equalizer effect may be used in the determination of the levels noise components, such as, inter-symbol interference power and neighbor cell interference power.
