Abstract

Over the past decade, there has been fierce competitions between the single carrier frequency domain equalization (SC-FDE) and OFDM systems. Efforts have been devoted in searching a better carrier scheme and waveform to deal with the complex channel environments. However, selecting one particular carrier paradigm to suit different channel scenarios is infeasible. In this paper, we propose a weighted fractional Fourier transform (WFRFT) based hybrid carrier scheme to integrate the existing SC-FDE and OFDM schemes under a unified physical layer architecture. By leveraging the concept of WFRFT, hybrid carrier (HC) scheme proposes a compatible process of SC-FDE and OFDM modulation. We demonstrate a running prototype based on the NI USRP and Xilinx's ZYNQ platform. The compatibility of the WFRFT-based HC scheme with conversational SC-FDE and OFDM architecture is presented. Experimental results validate the practicability and the carrier convergence capability of the proposed scheme.
