Detection of mutually orthogonal codewords, with intersymbol interference and imperfect timing |
摘要 |
Methods and systems are provided whereby correlations between a received signal sample set and a plurality of potential codeword data set are determined and a potential codeword with the highest correlation value is selected as the decoded codeword. The correlation of a potential codeword may be determined by computing a squared magnitude of correlation values between the potential codeword and the received sample set starting at various time points and then summing the squared magnitudes of the correlation values at those points. The number of time points used for correlation computation and summing depends on the time spread of the received symbol pulse. Furthermore, the correlations may be weighted before summing.
