| Abstract: | Now there are two common kinds of power inversion models for zero-trap in antenna array of the satellite navigation receiving system. One is the LMS （Least Mean Square） model with the reference signal, the other is LCMP （Linear Constrained Minimum Power） model. After the two models are briefly analyzed, their equivalence is theoretically approved though the inverse characteristic of the block matrix. Their different adaptive situations are discussed according to their characteristics. The validity of the theory is demonstrated through the simulation. This is the new reference for theoretical model construction, simulation, designation and application of anti-jamming zero-trap antenna in the satellite navigation receiving system. |
