摘要:
A Radio Frequency (RF) receiver includes a RF front end and a baseband processing module coupled to the RF front end that is operable to receive a time domain signal that includes desired signal and interfering signal time domain training symbols and time domain data symbols. The baseband processing module includes a channel estimator operable to process the desired signal and interfering signal time domain training symbols to produce a respective time domain channel estimates, a Fast Fourier Transformer operable to convert the time domain channel estimates to the frequency domain to produce frequency domain channel estimates, a weight calculator operable to produce frequency domain equalizer coefficients based upon the frequency domain channel estimates, an Inverse Fast Fourier Transformer operable to convert the frequency domain equalizer coefficients to the time domain to produce time domain equalizer coefficients, and an equalizer operable to equalize the time domain data symbols using the time domain equalizer coefficients.
