TRANSMITTING END, RECEIVING END, AND COEXISTENCE METHOD FOR SINGLE CARRIER SYSTEM AND MULTI-CARRIER SYSTEM

摘要

The invention provides a transmitting end, a receiving end, and a coexistence method for single carrier system and multi-carrier system. A signal transmission method that single carrier system can coexist with multi-carrier system comprises: the transmitting end modularizes a first frequency band corresponding to a first signal transmitted by a single carrier system to a second frequency band corresponding to a second signal transmitted by a multi-carrier system, so that a transmission signal at least including the first signal and/or the second signal is obtained, the distance between the center frequency point of a first sub-channel and the center frequency point of a second sub-channel is an integral multiple of the distance between two adjacent second sub-channels, and the signal bandwidth corresponding to the first sub-channel is less than or equal to the signal bandwidth corresponding to the second sub-channel; and the transmission signal is transmitted to the receiving end so as to accomplish the receiving of the first signal and the second signal. By means of the method above, the present invention can reduce mutual interference of the single carrier system and the multi-carrier system during signal transmission, guarantees that heterogeneous systems can share frequency spectrum resources, and improves the frequency spectrum utilization rate.
