Method for estimating discontinuous orthogonal frequency division multiplying channel based on compressed sensing

The invention discloses a method for estimating a discontinuous orthogonal frequency division multiplying channel based on compressed sensing. The method comprises the steps of: designing a channel estimating pilot pattern, selecting a pilot pattern and estimating a channel frequency domain response. The pilot pattern is selected by using two schemes. The first scheme is to maintain a traditional uniform pilot pattern and automatically disable a pilot at a disabled sub-carrier in order that an available pilot presents a natural non-homogeneity. The second scheme is to fix the quantity of the pilots and utilize the following optimized problems to search P sub-carrier transporting pilot marks in the available sub-carrier based on a criterion of recovering matrixes correlation minimization, wherein L is the channel length, P is the number of pilots, and N is the total number of OFDM system sub-carriers. The method of the invention can be applied to various scenes of the disabled sub-carrier. Through the method of the invention with fewer pilots, the acquired channel estimating property and system error ratio property are better than those acquired by using the other methods in prior art.
