Title of talk: Sequences with Low Correlations for Constrained Spectrum


Frequency hopping and direct spreading sequences having low correlation properties have contributed to growth and development of new generation communication access technologies. All these traditional methods assume the availability of contiguous band of spectrum. The spectrum in practice is a rear commodity, and the applications must invent novel technologies to reuse spectrum efficiently. New paradigms such as Cognitive Radio and Cognitive radar have the capability to sense the Radio Frequency environment and efficiently uses the spectrum by cooperative mechanisms. In this talk, we will go through limits on correlation parameters and their influence on sensing and subsequent detection in spectrum constrained environments. I will also talk about new directions in sequences with correlations
