The Apply of Eigenvalue-construct Method in Signal Distinguish of Multi-objects OFDM System
This paper analyzes the characteristic of OFDM's multi- path environment, proposes the method of distinguishing multi- objects signal on the basis of information of frame synchronization of OFDM,eigenvalue- construct method such as ESPRIT and MUSIC have been used joining with pseu- data correlative matrix method to estimate signal s DOA, thus could be used in subject of object identify.The following theoretical analysis and computer simulations help confirm its effectiveness in multi- objects identify and signal distinguish in OFDM system.
