Research on Out-of-Band Radiation of Cosine Family Signals Applied in FBMC System

As the most commonly used baseband signal, cosine signal is widely used in single-carrier system or multi-carrier system. In this paper, the cosine family signal is used, some suitable improvements are made to the traditional cosine signal to make it more suitable for the filter bank multi-carrier (FBMC) system with different overlap factors, and to make it show better ability in suppressing the out-of-band radiation (OOBR) of the FBMC system.
