OFDM is a kind of highly transmission technology. Its main idea is that the channel is divided into many sub-channels in the frequency domain and each sun-channel is modulated with a sub-carrier. Especially each sub-carrier is orthogonal and turns high speed serial data into low-speed parallel data stream modulated to each sub-channel. This paper is mainly discussed three interpolation algorithms and their characters in channel estimation by computer. We can use the conclusion to choose the correct interpolation algorithms in OFDM channel estimation.
