A clock synchronization method, a receiver, a transmitter, and a clock synchronization system, where the method includes obtaining a common reference clock signal, determining Baccording to the common reference clock signal and Mr(t−1), where 2. The method of claim 1 , wherein determining the Bcomprises:{'sub': 'd', 'o': [{'@ostyle': 'single', 'sub': 'sN(t−1)', 'f'}, {'@ostyle': 'single', 'sub': '(t−1)', 'T'}], 'performing, by the receiver, the frequency division on the common reference clock signal using the Mr(t−1) as the frequency dividing coefficient to obtain a second clock signal, a frequency of the second clock signal comprising , and a period of the second clock signal comprising ;'}{'sub': d', 't', 't−1', 'd', 't, 'o': {'@ostyle': 'single', 'sub': '(t−1)', 'T'}, 'performing, by the receiver, summation on Mrusing a formula B=B+Mr(t−1), and storing the Bobtained after the summation into a counter in the receiver when the starts; and'}{'o': [{'@ostyle': 'single', 'sub': 't', 'B'}, {'@ostyle': 'single', 'sub': 't', 'B'}], 'sub': t', 't, 'sup': p', 'p, 'obtaining, by the receiver, a new by calculation using a formula =B−2when the B>2.'}3. The method of claim 1 , wherein the Mr(t−1) comprises Mr(t−2) when the t is greater than one.4. The method of claim 2 , further comprising:{'sub': d', 'd', 't', 'd, 'generating, by the receiver, a new Mraccording to a value of the Mr(t−1) when the Cobtained by calculation according to the Mr(t−1) is greater than the threshold;'}{'sub': t', 'd, 'recalculating, by the receiver, the Baccording to the new Mrand the common reference clock signal;'}{'sub': t', 't, 'recalculating, by the receiver, the Caccording to the Bobtained after the recalculation; and'}{'sub': d', 'd', 't, 'determining, by the receiver, that the new Mrcomprises the target Mrwhen the Cobtained after the recalculation is less than or equal to the threshold.'}5. The method of claim 4 , wherein generating the new Mrcomprises:{'sub': t', 't, 'performing, by the ...
