Let X and Y are statistically independent Gaussian-distributed Let X and Y are statistically independent Gaussian-distributed random variables, each with zero mean and unit variance. Define the Gaussian process Z (t) = Z cos (2pt) + Y sin (2pt) (a) Determine the joint probability density function of the random variables Z (t1) and Z (i2) […]
Just as in an ordinary QPSK modulator, the output of a Just as in an ordinary QPSK modulator, the output of a p/4-shifted DQPSK modulator may be expressed in terms of its inâphase and quadrature components as follows; s(t) = s1(t) cos(2pfct) â sQ(t) sin (2pfct) formulate the in-phase component s1(t) and quadrature component sQ(t) […]
Let X (t) is zero-mean, stationary, Guassian process with Let X (t) is zero-mean, stationary, Guassian process with autocorrelation function RX (t). This process is applied to a square-law device, which is obtained by the input-output relation Y (t) = X2 (t), where Y (t) is the output (a) Show that the mean of y […]
