Consider a (4,4) MIMO channel with i.i.d. Rayleigh fading. The received signal isx = Hs + n, where the elements of the 4 x 4 channel matrix H are i.i.d. zero-meancomplex Gaussian random variables with unit variance. The average received poweris E(II s II2)= P, and the additive noise term n is a zero-mean AWGN vector with covariance E(nnH)= s2I4. Using a total transmit power of 100 milliwatts, the re-sulting received SNR is -10dB (P/s2 = 0:1). Evaluate the ergodic open-loop capacity COL(4; 4; 0:1). Share:by emailon facebookon twitter
