EMBEDDED MODULE RECEIVER NOISE PROFILING |
摘要 |
<p>A self-test prediction system predicts the impact that a host device has on an embedded wireless device's receiver performance by recording the wireless device's received power. No carrier or pilot signal is necessary to predict the impact. The wireless device's embedded receiver monitors its own received power (e.g., RSSI) from any type of radiated noise from the host device. For receivers that do not provide RSS referenced to absolute power, an external reference tone can be used in order to scale the measured receiver carrier to noise or signal to noise data to an absolute power. The increase in measured received power on the wireless device's receiver correlates to the impact the host device will have on the embedded wireless device's receiver sensitivity performance, providing a faster approach with less external equipment than current approaches that use external equipment to simulate the wireless device's forward link signal.</p> |
