Abstract

Research in cognitive radios has renewed interest in tools, such as spectrum estimation and modulation identification, to characterize the radio frequency (RF) environment. The use of multiple antennas for multiple-input multiple-output (MIMO) communications presents a new challenge in detecting and classifying signals. In this paper, we propose a statistical test to detect space-time block codes, focusing on the two transmitter Alamouti code. Our test exploits a new characterization of the Alamouti space-time block code (STBC) using fourth order cyclic frequencies. The test requires only a single receive antenna, and does not require any symbol synchronization.
