Abstract :
In this paper, we propose a new channel equalization using frequency and/or time spreading for UWB multiband OFDM schemes. The proposed equalizer is optimal in the least square sense, and does not increase complexity compared to classical equalizers. The performance of this equalizer is studied for channel delay spread below the guard interval
