We propose new algorithms for estimating autoregressive (AR), moving average (MA), and ARMA models in the spectral domain. These algorithms are derived from a maximum likelihood a...

In this paper we present the design process of an orthogonal frequency division multiplexing (OFDM) implementation for the Kansas University Agile Radio (KUAR). The KUAR is a porta...
