[0032]The interference detection method provided by the present invention will be described in detail below with specific examples in conjunction with the accompanying drawings.
[0033] figure 2 Point out the schematic diagram of the interference detection position in the OFDM communication system, the detailed interference detection process is not described here, you can refer to figure 2 learn.
[0034] Combine below image 3 The flow chart of the interference detection method of the present invention introduces the technical solution of the present invention in detail.
[0035] A method for detecting interference in an OFDM communication system, comprising the following steps:
[0036] Step 1: In the working frequency band of the OFDM communication system, the transmitter is turned off after sending a piece of data, and the receiver divides the received OFDM data into A (1) 、A (2) …A (i) …A (16) 16 sub-bands, the bit error rate of each sub-band is counted after de...
