Abstract

The inherent characteristic of hybrid carrier (HC) scheme based on the weighted-type fractional Fourier transform (WFRFT) is revealed.The proposed linear combination of single carrier (SC) and multi-carrier's (MC) characteristics is helpful to balance the conflicting requirements and achieve the comparative analysis of SC/MC.As an example, analytical SER/BER expressions of HC system with zero forcing (ZF) and minimum mean square error (MMSE) equalization are derived.In addition, the derived BER expressions are extended to multi-input systems.A unified framework of space time block code (STBC) HC scheme is proposed with two WFRFT modules at the transmitter or receiver,where STBC-SC and STBC-MC systems are the special cases of the novel structure.
