power of beamformed signals
显示 更早的评论
Hello,
I have a random signal 'x' of matrix dimensions 100x5000 i.e. I have 100 signals of 5000 samples each with fs=1000.
I want to find the power of these 100 signals and plot them versus angle(1:100) to view meshplot of the beam pattern.
How can I go about doing this? Please help.

What kind of signal you have? If you have a signal of WSS, you can probably use var directly.

Then you can to do var(signal-sin(2*pi*200*t). You need to be careful when you interpret the result because this way you measure the power of noise. Hence, at your desired location, you actually have least noise power.
