Abstract: The present invention discloses data receiving and sending methods and apparatuses and a system, and relates to the field of communications technologies. The data receiving method includes: receiving a data carrier; deciding polar radius values of multiple labeled constellation points carried at a pre-determined location in the data carrier, to determine a numerical value indicated by a polar radius value of each labeled constellation point in the multiple labeled constellation points; determining, according to a sequence including numerical values indicated by polar radius values of all the labeled constellation points in the multiple labeled constellation points, a demodulation scheme of a constellation point, other than the multiple labeled constellation points, carried in the data carrier; and demodulating, according to the determined demodulation scheme, the constellation point, other than the multiple labeled constellation points, carried in the data carrier.

Abstract: The present disclosure relates to an apparatus and method of processing a digital signal, wherein an input signal is transformed into the frequency domain by applying a fast Fourier transformation (FFT) processing to obtain a transformed input signal. Positive and negative frequency components of the transformed input signal are separated and respective ones of the separated positive and negative frequency components are separately processed by respective digital filtering to obtain filtered frequency components. The filtered frequency components are combined in the frequency domain using a down-sampling operation for down-sampling the filtered frequency components from an input number of samples per symbol to a different output number of samples per symbol, and the combined output components are converted into the time domain by applying an IFFT processing.
