Example Embodiment
[0026] see figure 1 , the implementation steps of the inter-cell delay difference compensation method in the coordinated multi-point transmission system of the present invention are as follows:
[0027] Step 1, establish the received signal model.
[0028] When the serving cell 0 cooperates with the cooperative cell 1, the signal received by the user is:
[0029] y = H 0 e - j 2 π τ ′ k / N FFT H 1 ...
