Embodiment Construction
[0019] Other purposes, characteristics and advantages of the present invention can be better understood through the detailed description of the embodiments of the adaptive modulation and demodulation control device and its implementation method according to the present invention below in conjunction with the accompanying drawings.
[0020] see figure 1 Describe the structure of the adaptive modulation and demodulation control device of the present invention. Such as figure 1 As shown, the adaptive modulation and demodulation control device is composed of a signal error estimator 101 , a forward error detection decision unit 102 , and an adaptive modulation and demodulation decision unit 103 . Among them, the signal error estimator 101 is used to estimate the error between the actual signal and the decision signal; the forward error detection decision unit 102 is used to check whether there is an error in the decoded bit stream; the adaptive modulation and demodulation decisio...
