I am having a little trouble with my Energy Detection simulation for spectrum sensing
expression 1 -> pf * gamma(u)= incomplete_gamma(u,lambda/2)
where pf = probab. of false alarm
u = Time-Bandwidth product
lambda = threshold
expression 2 -> pd = Q(sqrt(2*snr) , sqrt(threshold))
where Q()...
oh okay , so mskmod would create the complex envelope , which i can then multiply with a carrier wave ( e.g. cos (2*pi*890e6*t)) to have my msk modulated stream. and i wont have to do any odd and even sequence separationa dn then the separate multiplication. Am i Right ?
secondly , if i wanna...
I have 5 bursty bit streams which are to be modulated by MSK at different carrier frequencies.
The bit stream is zero ( if no signal is there) , or 1 or -1 ( 1-> logic 1 and -1 ->logic 0). each symbol ( 0 , -1 or 1 ) is sampled 8 times with the sampling interval = 4e-7 seconds.
How can I...
