Method and device of frequency domain equalization |
摘要 |
A method of a frequency-domain equalization to jointly suppress inter-symbol interference (ISI) and data-like co-channel interference (CCI) includes receiving a transmit signal over a channel, generating a vector by sampling and converting the transmit signal to a frequency domain signal; generating an equalized vector by multiplying an equalization matrix to the vector generated by converting; generating an estimate of data vector by inverse converting the equalized vector; and recovering data included in the transmit signal based on the estimate of data vector, wherein the equalization matrix is generated by approximating a frequency domain correlation matrix. Significant computational complexity is reduced than the LMMSE equalization while resulting in almost no performance degradation compared to the LMMSE equalization. |
