SIMPLIFIED PRACTICAL RANK AND MECHANISM, AND ASSOCIATED METHOD, TO ADAPT MIMO MODULATION IN A MULTI-CARRIER SYSTEM WITH FEEDBACK |
摘要 |
<p>A method of adapting transmission parameters in a multicarrier communication system having multiple transmit antennas and/or multiple receive antennas, whereby a statistical parameter of a wideband channel is computed, one type of matrix modulation scheme is selected to be used for a given multicarrier modulation symbol, one type of signal constellation is selected to be used for a given multicarrier modulation symbol, and one concatenated channel coding rate is selected to be used for a given multicarrier modulation symbol. Multicarrier modulation symbols are then transmitted using the selected matrix modulation scheme, signal constellation, and concatenated channel coding rate.</p> |
