Abstract

This paper proposes the architecture of UWB OFDM communication system. More high data rate is requested in the 128-point FFT/IFFT of the UWB OFDM communication system than the conventional communication systems. So, the proposed architecture uses pipeline and parallel architecture. For a highly efficient architecture, the optimal clipping power and the input quantization bits are found in simulation. The hardware complexity of the proposed architecture is presented is consideration of Adder, Register and Complex Multiplier.
