Apparatus and a Method

摘要

An apparatus including: addition circuitry configured to receive simultaneously a probe signal that has passed through a channel having a complex transmission and a reference signal and configured to produce at least: a plurality of weighted additions including an addition of the probe signal and the reference signal with different relative phase rotations between the probe signal and the reference signal for each weighted addition; and processing circuitry configured to use at least two of the plurality of weighted additions to determine a first quantitative parameter for the channel dependent upon the complex transmission for the channel.

1. An apparatus comprising:
addition circuitry configured to receive a probe signal that has passed through a channel having a complex transmission and a reference signal and configured to produce at least: a plurality of weighted additions comprising an addition of the probe signal and the reference signal with different relative phase rotations applied before addition between the probe signal and the reference signal and processing circuitry configured to use at least two of the plurality of weighted additions to determine a first quantitative parameter for the channel dependent upon the complex transmission for the channel.
