摘要:
A Radio Frequency (RF) transceiver 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 time domain training symbols and time domain data symbols. The baseband processing module processes the time domain training symbols to produce a time domain channel estimate, Fast Fourier Transformer operations that convert the time domain channel estimate to the frequency domain to produce a frequency domain channel estimate, weight calculation operations that produce frequency domain equalizer coefficients based upon the frequency domain channel estimate, Inverse Fast Fourier Transformer operations that convert the frequency domain equalizer coefficients to the time domain to produce time domain equalizer coefficients, and equalization operations that equalize the time domain data symbols using the time domain equalizer coefficients.
