The spectral efficiency of a frequency division multiple access system can be increased by allowing some spectral overlap of adjacent user signals, at the expense of higher interuser interference. We derive the linearized mean square error of pilot …
We propose an iterative decision-directed joint frequency offset (FO) and channel estimation algorithm in a known symbol padding (KSP) orthogonal frequency division multiplexing (OFDM) system, where the guard interval is filled with pilot symbols. …
This contribution deals with the carrier frequency offset estimation for a flat-fading Multiple-Input Multiple-output (MIMO) channel using a training sequence. The resulting Maximum Likelihood (ML) estimation entails solving a maximization problem …
