Method, system and application of decimetric wave hybrid beam forming

The invention belongs to the technical field of wireless communication, and discloses a decimetric wave hybrid beam forming method and system and application, and the method comprises the steps: inputting a signal to be transmitted, the number of sub-arrays, the number of antennas in each sub-array, a digital precoding weight vector which is adjusted according to MIMO space-time coding, and a phase difference between the antennas; obtaining an output signal of each power amplifier, and obtaining far-field response of the array through calculation; adopting an MP model as a nonlinear model of the power amplifier, and solving a DPD coefficient by using an output signal of an array and an input signal of a system in an indirect learning structure; and inputting the signal passing through the DPD into the system, and detecting the far-field response of the array until the DPD algorithm converges and the error meets the simulation set value. The method can well adapt to an offshore channel environment, is convenie
