RSSI MEASUREMENT METHOD, RSSI MEASUREMENT DEVICE, AND RECEIVER

摘要

The present invention provides an RSSI measurement method, an RSSI measurement device, and a receiver. The method comprises: measuring a digital domain RSSI output by a front end of a receiver; measuring channel noise power of the front end of the receiver; calculating a digital domain power dB value of a received signal according to the digital domain RSSI and the channel noise power; and calculating the difference between the digital domain power dB value of the received signal and the processing gain of the front end of the receiver, so as to obtain the RSSI of the front end of the receiver. In this way, during calculation of an RSSI, the impact of channel noise is eliminated, and a relatively accurate RSSI can be obtained, thereby solving the problem in existing measurement solutions of inaccurate RSSI measurement in cases of small signals.
