Abstract
A method, apparatus and system for transmitting signal, the method includes: using the weighting factor sequence, processing weighting repeating modulation for the basic cell block mapped by the data symbol block at the sending end, and obtaining a plurality of the repeating cell blocks corresponding to the said basic cell block; the sending end maps each repeating cell block to the appointed time-frequency position respectively, then sends the signals in the said time-frequency position; and the receiving end demodulates the plurality of data symbol blocks from the blocks, and incorporates the plurality of data symbol blocks; the said receiving end demodulates the incorporated data symbol blocks, and generates the received data. This scheme can be called for short as the block repeating spread diversity transmission technology, it is based on the information symbol in the time-frequency domain two-dimensional grid point. This scheme doesn't restrict the modulating signal generation manner at bottom, it can form a new multiple address/multiple path transmission scheme, and can be incorporated with the other key technologies in the existing mobile communication.
