Embodiment Construction
[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.
[0053] The first embodiment of the present invention relates to a constant-envelope co-frequency interference edge detection method. The position of the constant-envelope edge can be accurately found in the asynchronous co-frequency interference, which reflects the position of the received signal on both sides of the constant envelope edge under asynchronous co-frequency interference. The characteristics of the terminal signal and the characteristics of the interference signal, so that different strategies can be adopted according to the edge detection results, which is beneficial for the equalization module to demodulate data in different regions and improve the demodulation performance of the equalization module.
