Now from this image I know that there are multipath components(due to spreading of signal power across time).
I want to know that upto which time do I have to measure the power for a single symbol transmitted and how can I know that after a certain amount of time the second symbol will start.(how can i measure that certain amount of time?)
In this received power I know that(by spreading) that there are multipath components. I want to measure the Gain of those multipath components. So how can i sample it and how do I know about number of multipath components?
