[0031] see figure 2 , is a decoding method applied to the above-mentioned spectrum detector 100 provided by the embodiment of the present invention, which will be combined below figure 2 Describe the steps involved.
[0032] Step S101: Receive a radio signal.
[0033] When the spectrum detector detects a radio signal, it receives the detected radio signal.
[0034] Step S102: Determine whether the encoding method adopted by the radio signal can be identified based on a preset method.
[0035] After receiving a radio signal, if you want to further know the content contained in the signal, you first need to demodulate the received radio signal to obtain the demodulated signal, and then decode the modulated signal. Because the received radio signal is not a signal coded according to a pre-agreed coding method, but an unknown signal whose coding method cannot be predicted. Therefore, it is necessary to determine whether the encoding method adopted by the radio signal can be ...

[0117] As an implementation, please refer to Figure 7 , provides a decoding method applied to the above-mentioned spectrum detector 100 for this embodiment, which will be combined below Figure 7 Describe the steps involved.
[0118] Step S401: Receive a radio signal.
[0119] This step is the same as step S101, please refer to step S101 for specific description.
[0120] Step S402: Determine whether the encoding method adopted by the radio signal can be identified based on a preset method.
[0121] This step is the same as step S102, please refer to step S102 for specific description, wherein, if the encoding method adopted by the radio signal cannot be identified, in addition to generating an error report, that is, executing step S405, step S406 is also executed.
[0122] Step S403: Determine whether a decoding method corresponding to the coding method adopted by the radio signal can be found.
[0123] This step is the same as step S103, please refer to step S103 for sp...
