Performance Analysis of 4-WFRFT Based Carrier Modulations under Burst Interference

Abstract:

This paper proposed a 4-weighted fractional Fourier transform (4-WFRFT) based carrier modulation technique. The system performance applying such modulation is analyzed under burst interference, and then compared with single carrier (SC) modulation and multi carrier (MC) modulation based systems. Simulation results show that 4-WFRFT system achieves a better performance than those of SC and MC systems since the 4-WFRFT has the capability to disperse the energy of interference signals in fractional Fourier transform domain. When the SIR of burst interference is -2dB, there is no error floor occurs in 4-WFRFT system, while the error floor appears in both SC and MC systems.
