Embodiment Construction
[0025] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0026] The present invention provides a method for adaptively adjusting the modulation and coding mode in the communication system, which automatically adjusts the modulation and coding mode according to the CINR statistical value, and adjusts the CINR threshold corresponding to each modulation and coding mode through the BLER statistical value, figure 1 It is a flow chart of the present invention for adaptively adjusting the modulation and encoding method, and the specific steps are as follows:
[0027] Step A, the calculation of CINR statistical value:
[0028] Calculate the multi-frame average value of the CINR measurement value, and then remove the abnormal value of the CINR measurement value according to the multi-frame average value, and use the average value of the remaining frames after removing the abnormal value as the CI...
