WebJan 1, 2014 · 2.2 Energy Detection. The conventional energy detector measures the energy associated with the received signal over a specified time duration and bandwidth. The measured value is then compared with an appropriately selected threshold to determine the presence or the absence of the primary signal. WebWhen the first release of LTE (Rel-13) with operation in unlicensed spectrum was specified, a maximum energy detection threshold of −72 dBm, in between the two thresholds of −62 dBm and −82 dBm used by Wi-Fi, was chosen as a compromise, with the agreement to align all technologies around this single common maximum threshold in the long term. WebTherefore, another plan called optimal threshold based energy detection scheme was put forward [11-12]. However, the threshold level optimization which is based on minimizing the errors in spectrum sensing did not look ... multiuser wireless communication system to provide efficient use of radio spectrum [16].
