Block ICA for image suppression and carrier frequency offset correction in diversity BPSK receivers
Thomas Yang, Wasfy B. Mikhael · 2006
Abstract:- The image rejection and Carrier Frequency Offset (CFO) compensation are two important radio receiver functionalities. In this paper, the two problems are approached digitally at baseband adopting block ICA algorithms. For diversity BPSK receivers, the proposed technique results in simplified analog front-end. Simulations are performed assuming typical CFO and fading conditions. Satisfying performance is achieved with reasonable computational complexity.
