Abstract:
1. A receiver in a 2×2 Line of Sight (LoS) Multiple Input Multiple Output (MIMO) system, the receiver being arranged to estimate a first (ŝ 1 ) and a second (ŝ 2 ) signal on the basis of a first (r 1 ( t )) and a second (r 2 ( t )) signal received from respective first and second transmitters (Tx 1 ,Tx 2 ), said received signals (r 1 ( t ), r 2 ( t )) comprising a first (s 1 ) and second (s 2 ) signal, the receiver comprising a first Phase Locked Loop (PLL) and a second PLL, which are arranged to respectively determine a first (In the receiver further comprising an equalizer which is arranged to estimate the first (ŝ the equalizer further being arranged to compensate for an independent rotation frequency ftr
