- Totally Blind Channel Estimation for OFDM on Fast Varying Mobile Radio Channels
- A new blind channel estimation scheme for OFDM-systems is proposed based on the ML-principle. By avoiding the use of second- and higher-order statistics, a very fast convergence rate is achieved. A novel approach is also proposed for resolving the phase ambiguity of the blind channel estimate without the need for...

- Totally Blind APP Channel Estimation for Mobile OFDM Systems
- A new two-dimensional blind channel estimation scheme for coherent detection of OFDM signals in a mobile environment is presented. The channel estimation is based on the A Posteriori Probability APP calculation algorithm. The time-variant channel transfer function is completely recovered without phase ambiguity with no need for any pilot or...
