Abstract :
A new approach in HF channels parameters estimation is presented. It permits the improvement of the link quality analysis procedures involved in the link establishment techniques. This is achieved thanks to the estimation of the parameters that completely define the most widely used HF channel model: the Watterson (1970) model. The estimation method is based on the computation of the correlation function of the equivalent baseband output signal together with a least squares method. Performance analysis and simulation results are presented.
