A fast approximate joint diagonalization algorithm using a criterion with a block diagonal weight matrix
We propose a new algorithm for Approximate Joint Diagonalization (AJD) with two main advantages over existing state-of-the-art algorithms: Improved overall running speed, especial...

Iterative channel estimation and turbo equalization for time-varying OFDM systems
We develop a new receiver for orthogonal frequency division multiplexing (OFDM) systems in time-varying channels by embedding channel estimation in a low-complexity block turbo eq...
