Disclosed are a method, an apparatus, a receiver, and a communication device for estimating phase noise, and wherein the method comprises the following steps: obtaining the sending symbol ã(k) which is corresponding to the equalized symbol r(k) of received data, in which k=0,...,K-1, and K is the symbol number of one received data frame; obtaining public phase noise based on r(k) and ã(k); obtaining residual phase noise based on r(k), ã(k), and said public phase noise; obtaining the phase noise based on the public phase noise, the residual phase noise and the basis function matrix of Discrete Cosine Transform. The technical solution of the present invention can estimate the phase noise effectively, then compensate the receiving signals which are influenced by the phase noise, achieve the purpose for accurately detecting the sending symbol, and improve system performance. |
