Abstract
The present embodiments are directed to systems and methods for detecting random access channel requests, while excluding false random access signals using search windowing and distance-based peak suppression techniques. The present embodiments additionally include further techniques for suppression of fake random access signals, including amplitude thresholds and preamble-based signal exclusion. Beneficially, the present embodiments significantly reduce the false alarm rate, while maintaining a low hardware complexity requirements. In some embodiments, worst-case false alarm rates can be reduced from as much as 20% down to nearly 0.1%.
