| Abstract(in English) | Frequency domain equalization (FDE) has been studied for preventing performance degradation due to frequency selective fading in single carrier transmission. In fast fading environments, however, another problem occurs since cyclicity in the FDE block is lost. Thus, we have proposed subblock processing at the receiver side with pseudo cyclic prefix (CP) generation. The performance highly depends on the CP accuracy. Therefore, here, we apply a higher order interpolation method for more accurate channel estimation. In addition, overlapped subblock processing is used to reduce an effect of degradation in pseudo CP accuracy. The simulation results show performance improvements by applying these techniques to the subblock processing. |
