Multirate Space-Time-Frequency Linear Block Coding

Abstract

This paper presents a multirate space-time-frequency linear block coding scheme (STFBC) with full transmit diversity for a variety of transmission rates. The proposed multirate STFBC can achieve relatively smooth balance between the performance and the transmission rate for a given constellation size. Design of a space-time linear block coding (STBC) scheme is presented as a special case of the proposed multirate STFBC, which perform better than some of the existing STBCs. Moreover, optimized multirate STFBCs have also been compared with some of the existing STFBCs. Simulations results show that the design parameter has sufficient flexibility to achieve improved performance with reduced computational complexity. Show more
