Abstract: |
The invention belongs to the technique area of the signal transmission. The signal frame in the invented method is composed of a segment of the time domain pilot frequency and an overall data block. The overall data block is the statistical multiplexing of the small data blocks, which use multi-carrier modulation or single carrier modulation. The length of the overall data block is variable. In grouped data communication, the overall data block is divided into M sub blocks M is greater than or equal to 2, transferring total N information symbols. The head information of the overall data block describes the sizes, positions and modulation modes of each sub blocks. Based on the head information, the receiver carries out different treating the demodulation for each sub block. |
