Linear MMSE receiver using hidden training sequence in DS/CDMA - Electronics Letters

Numerical results and conclusions: Although the previous analysis also applies to frequency selective channels, for simplicity we consider the example of a flat fading channel with the channel impulse response z(r, I ) = [c0 + a,z , ( f ) ]S(r ) , where x: is the power gain of the diffise beam and z,(l) is a zero-mean, unit variance complex Gaussian random process representing the time-varying fading process. The correlation matrix, Rh is assumed to correspond to that typically encountered in land mobile channels as used in [3].
