The invention discloses a joint encoding modulation method based on no-rate codes and V-OFDM. A sending terminal conducts modulation based on the no-rate codes and the V-OFDM. The joint encoding modulation method is basically characterized by comprising the steps that 1, a message bit stream which is encoded through no-rate codes is mapped into a time-frequency domain message matrix of Vector OFDM, and the area degrees of a data block are even; 2, message bits encoded through the no-rate codes are modulated to subcarriers, the message bits of different freedom degrees are mapped onto the same subcarrier, and the message bits of the same freedom degree are mapped onto different subcarriers. According to the joint encoding modulation method, through joint encoding modulation, frequency selective fading and time selective fading of a doubly selective channel can be more effectively resisted, intersymbol interference and carrier interference are overcome, doubly selective fading is effectively resisted, bigger joint multipath-Doppler diversity gain of the doubly selective channel is obtained, the error rate is lowered, and the communication quality is improved.
