Abstract

Superposed multicarrier transmission is a potential solution to the spectra overcrowding problem in wireless communications. Powerful FEC coding using a turbo code is one way to overcome the increased noise power due to the interference. Reliable decoding of turbo codes requires accurate knowledge of the channel coefficients and the power of the interference if it is present. This paper presents soft-decision-aided, joint MAP estimation of these parameters, which requires only a small pilot overhead. A novel superposed band detection method is also proposed. The accuracy of the estimators and the effectiveness of the superposed band detection are demonstrated via simulations.
