1. A data receiving method, comprising:a receiving end receiving a plurality of subframes transmitted by a transmitting end;
the receiving end determining time-frequency resources onto which a plurality of transport blocks are mapped in the plurality of subframes; and
the receiving end jointly demodulating a plurality of transport blocks in the time-frequency resources;
wherein the receiving end jointly demodulating a plurality of transport blocks in the time-frequency resources comprises:
demodulating a first transport block, demodulating data of a first transport block in M transport blocks as a predetermined demodulation order according to a channel frequency domain response of a pilot signal, wherein M is positive integer which is greater than or equal to 2;
calculating a channel frequency domain response, coding and modulating demodulated data of a current transport block, obtaining a channel frequency domain response corresponding to data in the transport block by channel estimation;
demodulating subsequent transport blocks, demodulating data of a next transport block by using the obtained channel frequency domain response; and
calculating the channel frequency domain response and demodulating the subsequent transport blocks repeatedly until all transport blocks have been demodulated.
