In order to transmit data correctly, these users usually need to use narrowband transmission, such as one or more 15 kHz subcarriers, which will transmit The power concentrates on the narrowband to transmit signals, improves the SNR or SINR of the received signal, and further, it can also combine the repeated transmission in the time domain and/or the extended transmission to improve the SNR or SINR of the received signal.

However, in practice, some transmission timings or transmission frequency resources are not well utilized, and the transmission performance is poor.

The sequence may also be called a code, and the sparse meaning is from a generalized In the above, it can be considered that there are zero elements in the sequence or pattern. In a narrow sense, it can be considered that the proportion of zero elements in the sequence or pattern is not less than a certain value (for example, 50%), and non-orthogonal refers to the available sequence as a whole. Or the pattern is non-orthogonal, and it is not excluded that some of the sequences or patterns are orthogonal. 1 is a schematic diagram of a sparse sequence or sparse pattern of length 4 in the related art.
