Efficient implementation for equalization of multicarrier channels |
摘要 |
A system and method for minimizing the effective channel impulse response in multitone communication systems, is provided. A time domain equalizer is utilized to shorten the channel impulse response to a length equal to or less than the time duration of the cyclic prefix. The time domain equalizer includes an adaptable filter with updateable coefficients. The updateable coefficients are calculated in a storage efficient manner to effectively estimate a desirable channel response. Processing of the time domain equalizer signal improves the symbol boundary estimate and effectively reduces the effect of noise of the updateable coefficient solution.
