SAME-FREQUENCY SIGNAL INTERFERENCE MEASUREMENT METHOD AND RECEIVER

摘要

Provided in an embodiment of the present invention are a same-frequency signal interference measurement method and receiver, the method comprising: acquiring the precise signal-to-noise ratio of a lower power signal in the case of no same-frequency signal interference according to measured temperature and prestored noise factors; controlling the transmitting power to acquire the signal-to-noise ratio and receiving power of at least one group of receivers, and acquiring the signal-to-noise ratio of the low power signal during operation; and calculating the interference power according to the difference between the signal-to-noise ratio of the lower power signal in the case of no same-frequency signal interference and the signal-to-noise ratio of the low power signal during operation. The minimum measurable interference power is -107dBm; a transmitter has the power adjustment range of 23dB; and the measurement can be completed within seconds.
