Detection Data Detection Given the demodulator output, determine the transmitted symbols MAP Detection Rule or equivalently:
Detection ML Detection Rule: (assumes all inputs are equally likely) Vector AWGN Channel: Y = X + n . The noise vector n is N –dimensional Gaussian random vector, with zero mean, equal variance, uncorrelated components with distribution
MAP Detection AWGN Channel: Y = X + n MAP Detection:
AWGN MAP/ML Detection Equivalently, AWGN ML Detection: Question : What if the noise is correlated with correlation matrix ?
