Abstract
The present invention discloses a pilot frequency position determining method based on pilot frequency interval optimization and a transceiver device. The method optimizes a pilot frequency position on the basis of better use of pilot frequency in a wireless system for sampling frequency synchronization and residual phase tracking. After an optimal pilot frequency position is obtained according to the method, a transmitting terminal inserts a pilot frequency sequence at a corresponding pilot frequency position, a receiving terminal learns the pilot frequency position and the pilot frequency sequence, and after channel equalization, deviation is tracked by means of coherent detection of a local sequence. For the aforementioned method, the present invention further provides a transceiver device of a related pilot frequency module in the wireless system. The pilot frequency position can be better determined without increasing system complexity, and the present invention significantly improves the system performance.
