Totally blind channel estimation for OFDM on fast varying mobile radio channels.

Totally blind channel estimation for OFDM on fast varying mobile radio channels.

A new blind channel estimation scheme for orthogonal frequency division multiplexing systems is proposed based on the maximum likelihood 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 th...
