Since MMDS communication technology adopts digital filtering and digital storage, people can eliminate the noise accompanying image transmission in a very simple way to improve the signal-to-noise ratio of image transmission. In addition, digital filtering used in MMDS technology And the digital storage method is also very easy to achieve adaptive two-dimensional, three-dimensional brightness separation, completely eliminate the brightness interference; and other measures to improve the image quality, so that the image quality of the digital TV signal transmitted through the MMDS system is better than that transmitted through the ordinary way. The signal quality is much higher.
MMDS communication system uses digital compression transmitter to greatly reduce the number of analog transmitters, and considering the cost of construction, the digital transmission system is several times lower than the cost of using the corresponding analog transmitter. More investment than the laying of communication cables. The image quality is equivalent to the optical cable transmission quality, which is much better than the analog transmission quality, and its reliability is much higher than that of the optical cable transmission. If the provincial and municipal levels have adopted MPEG-2 digital compression transmission, then the county and township levels do not have to solve the compression equipment themselves.
