摘要： A device (20) for an adaptive modulation communication system is provided. The device (20) comprises an input device (21) adapted to receive, from a communication channel, data encoded through a FEC code. A FEC decoder (23) connected downstream of the input device (21) is also provided for FEC decoding the received encoded data and providing error information determined by the FEC decoding. The device according to the invention further comprises means for measuring first error information of the encoded data before FEC decoding the received encoded data, and means for measuring second error information determined by the FEC decoder (23). Means (25) for estimating a condition of the communication channel based on both the first error information and the second error information are also provided.

摘要： A method for phase noise detection in a MIMO communication system comprises the step of computing an initial estimate of phase using received pilot symbols. A phase follows for interpolating between successive pilot symbol phase estimates to obtain a coarse resolution reference phase estimate. Then, it follows a phase for computing a fine resolution estimate of phase using said coarse resolution phase estimate together with data expressing characteristics of known phase noise processes, applying an expectation maximization (EM) algorithm. The application of the EM algorithm can be further refined using improved symbol decisions from a FEC decoding.
