Impact of Linear Prediction Coefficients on Totally Blind APP Channel Estimation

  title={Impact of Linear Prediction Coefficients on Totally Blind APP Channel Estimation},
  author={Marc C. Necker and Frieder Sanzi},
Totally blind APP channel estimation is based on the A Posteriori Probability (APP) calculation algorithm. Asymmetrical modulation schemes are used in order to resolve the phase ambiguity with no need for any pilot or reference symbols. In OFDM-systems, the two-dimensional channel estimation is performed by applying a concatenation of two one-dimensional APP estimators for frequency and time direction in combination with an iterative estimation and decoding loop. Linear filters are used to… CONTINUE READING
