APPARATUS AND METHOD FOR ESTIMATING INTERFERENCE AND NOISE IN A COMMUNICATION SYSTEM |
摘要 |
A method and apparatus for estimating interference and noise power in an orthogonal frequency division multiplexing/orthogonal frequency division multiple access/discrete multi-tone (OFDM/OFDMA/DMT) system is disclosed. A correlator correlates a plurality of sub-carriers with a preset reference sequence on an element-by-element basis and outputs a result of the correlation. A signal noise producer calculates a difference between a correlation value associated with each of the plurality of sub-carriers outp ut from the correlator and a correlation value produced from at least one adjacent sub-carrier and outputs a result of the calculation. An interferenc e and noise power producer produce interference and noise power from the difference between the correlation values calculated by the signal noise producer. |
