摘要: An equalizer for a multi carrier transmission system, converts transmitted signal into sampled frequency domain signals, and suppresses time delay dispersion, on the signals. It exploits circulant decomposition of Toeplitz matrix to enable computationally heavy evaluation multiplied by vector, be avoided. Increased precision arises from processing being equivalent longer FIR filter than is normally practical. The amount compensation different carriers can adjusted, which lead increased precision.
