Independent component analysis for carrier synchronization in OFDM systems

Abstract: To overcome the inter-carrier interference (ICI) of orthogonal frequency division multiplexing (OFDM) systems due to the carrier frequency offset (CFO), an ICA-based carrier synchronization method is proposed. Independent component analysis (ICA) is also known as blind source separation (BSS), which depends on the independence of source signals to separate or extract latent signals of interest. In this paper, we build an analogous ICA model for OFDM systems with the CFO. By virtue of this model, the ICA techni… Show more
