摘要：A joint frame synchronization and reversed spectrum signal differentiation method for DRM Plus digital broadcasting systems is proposed. The proposed scheme can detect the fast frame synchronization and determine whether normal spectrum signal or reversed spectrum signal without carrier frequency offset & sampling frequency offset compensation, enabling fast frame synchronization. The proposed method shows outstanding performance in environments where symbol timing offsets and sampling frequency offsets exist.
