Abstract

A technique for detecting an orthogonal frequency division multiplexing (OFDM)-based signal at an ultra-wideband (UWB) module is disclosed. The technique involves receiving radio frequency (RF) energy at the UWB module, wherein the RF energy may include a cyclically extended OFDM symbol having a cyclic prefix and an OFDM symbol, downconverting the received RF energy into a baseband signal, autocorrelating the baseband signal to identify a match between the cyclic prefix and the OFDM symbol, and providing an output that indicates the presence of an interfering OFDM-based signal when a match is found between the cyclic prefix and the OFDM symbol.
