1. A method of optimizing the utilization of white space based on the enhancement of the adjacent frequency, characterized in that, by obtaining an available white space frequency and compensating the upper and/or lower adjacent frequencies respectively according to the relationship between the coverage of its adjacent frequency authorized signals and the coverage of the white space device, so that the white space device can obtain the maximum number of selectable channels and the maximum transmission power without affecting the existing adjacent frequency authorized signals;
the said relationship refers to: whether there is an overlap between the preset transmission coverage of the white space device and the authorized coverage of adjacent frequency signals;
the said enhancement of the adjacent frequency is to use the adjacent frequency compensation device to increase the transmission intensity of the authorized signal of the upper and/or lower adjacent frequency, compensate for the interference generated by the white space device, and to optimize the reception margin of the original upper and lower adjacent frequency transmission signals.
