| Abstract(in English) | This paper discusses effective frame structure for single carrier block (SCB) transmission in a double selectivity environment. For performance comparison, the M-sequence is used as the training sequence (TS) for the first block of each frame, and the frame is configured by the number of data blocks and the number of symbols per data block between the TS, where a cyclic prefix (CP) is added to each block to compensate for the delay spread. The channel interpolation (CI) method is used to improve tracking capability on time-varying channels. Since the interpolation accuracy of channel estimation depends on the size of the TS spacing, tracking capability of mobility depends on the number of data blocks between TS and the number of symbols per data block. Computer simulation evaluates the effective frame configuration for SCB transmission systems for time-varying channels, and also confirms that CI significantly improves tracking capability. |
