A pratical demonstration of spectrum sensing forWiMax based on Cyclostationary Features

In this paper, we present a Software Defined Radio (SDR) spectrum sensing demonstrator, based on the analysis of the cyclostationary signatures of a digital communication signal. We define a cyclostationary signature as a feature which is not intentionally embedded in a digital communications signal, but can be detected through cyclostationary analysis and used as a unique identifier. We present a theoretical discussion followed by a practical demonstration on a SDR platform. The demonstrator is used to analyze WiMAX 802.16d digital communication signals. We compare the performance of the spectrum sensing algorithm based on cyclostationary analysis with the one based on energy detection. The paper describes the main constraints and trade-offs, which influenced the design of the demonstrator. The probability of false alarm and the probability of missed detection are computed and the results are presented for different sets of the demonstrator parameters.
