Question

We consider a Rayleigh fading signal. Suppose that a single branch receiver has a 10% chance of being 5 dB below a certain SNR threshold gamma o. a) Determine the mean of the Rayleigh fading signal as reference to the threshold mentioned in the above, ie., gamma_o. b) What is the probability that the receiver signal will be 8 dB below gamma o if b1)a single branch receiver b2)a two branch selection diversity receiver b3) a three branch selection diversity receiver, or b4) a four branch selection diversity receiver is used, respectively.

Explanation / Answer

a)if X= x+iy;where x,y are independent and normallu ditributed variables.

if X is a signal then E{(x)^2} is indeed power of v.

so using this we can determine the mean of the rayleigh fading signal.

b)when the interfere signals are more than one,it becomes very difficult,it is not possible to obtaina tractable closed from expression of the probability density functionor cumulative density function of SINR or SIR
