v[n x[n] - 12[n] Figure Q1c) ս[ո] - O y[n] Given the scenario in Figure Q1c), now have in v[n] = 0 a zero mean uncorrelated signal with power of = 4 that is uncorrelated with u[n]. Further, we know that with u[n] being zero mean unit variance uncorrelated, the cross-correlation rux[t] between u[n] and x[n] is (+1 rux[1 + 1), T< 0 rux[T] 1, t=0 0, T>O What is the new power spectral density of the signal x[n]? Without explicit calculation, might this increase or decrease the coding gain w.r.t. Q1c)? -={
