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.
