N2 - Extension of signal representation from traditional time/frequency domains to space/code domains helps in designing innovative wireless communication systems with a significantly enhanced performance. However, the conflict between an increasing demand for wireless communications and a limited spectrum still remains a challenging issue. This article aims to explore another new way for signal representation. In particular, we investigate the feasibility of representing signals in a statistical spectrum domain for wireless communications. On the basis of signal cyclostationary features, cyclic delay diversity (CDD) orthogonal frequency division multiplexing (OFDM) is proposed in this article as an effort to demonstrate the ways of representing wireless signals in the statistical spectrum domain, based on which we will also show its data transmission and multiple access schemes.
