Design and Performance Analysis of Enhanced Receivers for Spectrally Efficient FDM System

چکیده
Spectrally Efficient FDM systems (SEFDM) promise increased spectral utilization at the cost of receiver complexity. In this paper, new reception arrangement for SEFDM system is proposed and analyzed. The signal demodulation is based on the subcarrier structure of the signal. Simple implementation based on the Discrete Fourier Transform (DFT) is introduced, thus significantly reducing the complexity of the receiver. Furthermore, the optimum detector for the system is derived. Numerical evaluation based on the error performance confirms identical performance with the originally proposed SEFDM receivers.
