| Abstract(in English) | Frequency-domain equalization (FDE) has been studied as a very simple countermeasure against frequency selective fading in a single carrier transmission system. In a fast fading environment, however, the equalization performance degrades since periodicity of the channel within an FDE block is lost. Therefore, we have proposed a method dividing a received data block into multiple subblocks to decrease the channel transition within the block in such an environment. In this method, the performance is degraded by inaccuracies of pseudo CP processing, which is introduced to satisfy periodicity in each subblock. In this paper, we study the application of frequency-domain turbo equalization (FDTE) to subblock processing for improving the accuracy of pseudo CP. The simulation results show that FDTE with subblock processing yields remarkable performance improvements. |
