The present invention relates to a
link adaptation method for a multi-mode communication
system, comprising the following steps: defining a
priority list for waveforms, and defining a
signal quality evaluation criterion for each waveform; sequentially monitoring the real-
time signal quality of each waveform according to the
priority list for waveforms, if it is detected that the
signal quality of any waveform exceeds a preset threshold indicating good
signal quality, determining the waveform as an optimal waveform, and otherwise, recording the current
signal quality of the waveform; if none of the waveforms meets a criterion for good
signal quality, selecting a waveform having the smallest difference as the optimal waveform; and dynamically adjusting the
priority list and the threshold criterion on the basis of the
system and
user feedback, so as to improve the accuracy and efficiency of future decision-making. The problems of insufficient decision criteria and a single condition in multi-mode waveform switching technology are solved, resources can be effectively managed and allocated, and waveforms having good
signal quality can be preferentially processed, thereby improving the response speed and efficiency of the overall
system, and maintaining the optimal performance.
