Have someone simulated the algorithm of energy detection spectrum sensing on labview communication design ?

[emnajaoua]

Actually I am using as hardware USRP 2901 as transmitter and as a receiver.I have implemented the energy detector algorithm in labview communications design using FSK modulation.

The problem that I don't know if the figures that I have got are valid or not because they don't look like what I have simulated on matlab.

You will find attached my figures of simulation of energy detector using QPSK modulation on matlab and my figures of implementing the energy detector algorithm on labview communicatiion design using BFSK modulation.

Hi Emanjaoua,

I didn't get a chance to look at your code, but looking at your results it looks like you might not have graphed your SNR on a decibel scale.

Cheers
