Now from this image, I know that there are multipath components(due to spreading of signal power across time).
I want to know that up to 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 the number of multipath components?
