In this study, the authors present a new criterion which can be used to decompose the coding advantage (CA) of space–frequency block codes (SFBCs). The proposed decomposition separates the CA into two parts, called precoder-CA and channel-CA. The precoder-CA represents the effects of the precoder and the signal constellation, and can be used in the design(More)
In this paper, we describe how full-diversity quasi-orthogonal space-time-frequency block codes (QOSTFBCs) suffer from low coding advantage. Then, we propose a method for improving the coding advantage of this code family, and we subsequently modify their performances. Simulation results determine that our proposed method is very effective, and in some(More)
Based on field extensions we propose a novel aspect for designing linear dispersion space-time block codes (STBCs). The proposed code achieves the maximum attainable diversity. This code is also full-rate and proved to be information lossless. The simulation results also show that the proposed scheme outperforms the Golden code when BPSK constellation is(More)
