This paper presented novel Carrier Frequency Offset (CFO) acquisition together with multi-antenna channel estimation algorithms for burst-mode Multiple-Input Multiple-Output combined with Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems. The new algorithms take full advantage of some known channel information (for example, the length of channel impulse response L which can be estimated...
In this paper, we derived joint frequency synchronization and channel estimation algorithms MIMO-OFDM systems (Multiple-Input Multiple-Output & Orthogonal Frequency Division Multiplexing). Although the new estimator is also based on Expectation Maximization (EM) algorithm, but unlike traditional estimator the new one utilized some known channel parameters to achieve estimator Matrix Dimensionality...
This paper examined the problem of carrier phase recovery in turbo-coded OFDM systems. Then introduced a novel a priori probability aided (APPA) OFDM joint carrier phase recovery and signal detection algorithms to eliminate disadvantage impact brought by phase offset. The algorithms utilized the soft value of the extrinsic information generated by iterative maximum a posteriori (MAP) turbo decoders...
