Frequency Domain Equalizer Using Zero-padding for IR-UWB Systems

In this paper, we propose a zero padded single-carrier (SC) block transmission with minimum mean squared error-frequency domain equalization (MMSE-FDE) for impulse radio ultra-wideband (IR-UWB) systems. Moreover, the comparative study among the proposed scheme and the conventional one is presented. The proposed zero padded MMSE-FDE not only has the favorable advantages of the existing cyclic prefixed SC-FDE, but it also overcome the power loss due to the usage of the cyclic prefix. The validity of the proposed algorithm is demonstrated by simulation results with relevant discussions.
