Abstract
A transmit processor that includes a transmit frequency domain equalizer (TX FEQ) that pre-compensates packets in the frequency domain to flatten transmit filter response to improve the spectral mask and reduce packet error rate (PER). The TX FEQ taps may be selected so that the average power at the output equalize the average power applied to the input. The TX FEQ may be designed to yield 64 QAM packets with no quantization distortion at the input of the an Inverse Fast Fourier Transform (IFFT) processor. The 64 QAM constellation map points and TX FEQ gain values are selected to avoid exceeding the bit resolution of the IFFT processor. The tones may be bound together into zones to reduce implementation complexity by reducing the number of TX FEQ taps.
