Abstract:

Based on the singlecarrier frequency domain equalizer(SCFDE)approach providing immunity of intersymbol interference (ISI), a novel frequency domain balanced structure for ultrawideband system was proposed. The optimal frequency domain balance algorithm based on minimum meansquare error (MMSE) estimation wais introduced. The simulation result shows that the bit error ratio can be decreased greatly.

Key words: ultrawideband, minimum meansquare error, fast Fourier transform
