The invention belongs to the technical field of the modulation carrier system, and discloses an iterative detection method of joint channel estimation in a FBMC system. The method comprises the following steps: eliminating interference in a first-order neighbor domain by using auxiliary pilot to accomplish a channel initial estimation value; estimating the interference out of the first-order neighbor domain by uniting the iterative detection, and feeding back the interference to modify the channel initial estimation value, thereby improving the estimation precision and acquiring an accurate detection result. Compared with the traditional orthogonal frequency division multiplexing technology, and the multi-carrier technology of a filter bank has higher spectrum use ratio, lower out-of-bandinterference and better synchronization robustness without using the cyclic prefix. Since the FBMC/OQAM system satisfies the orthogonality at the real-number field, and inherent imaginary part interference is existent in the complex field, and the great challenge is brought to the channel estimation. The simulated analysis result shows that the algorithm provided by the invention is fast in convergence rate and high in estimation precision.
