Performance of Universal Filtered Multicarrier Channel Estimation with Different Pilots arrangements

Abstract

Universal Filtered MultiCarrier(UFMC) is a spectrally efficient waveform that applies per-subband filtering to reduce the Out Of Band emissions. Thanks to the orthogonality in complex plane, UFMC retains the simplicity of conventional OFDM while addressing its drawbacks. One of the main advantages of UFMC is its compatibility with the existing OFDM techniques. For instance channel estimation can be built based on OFDM one. Hence in this paper, we address the pilot aided channel estimation. To this end we propose to use the scattered pilot arrangement for UFMC under a fast varying channel. The results reveal that despite the difference in channel gain between subcarriers in UFMC, scattered pilot arrangement has good performance with the minimum number of pilots compared to block and comb type arrangement.
