Abstract

The invention provides a communication method and system based on a filter. The method comprises the steps of carrying out the low-frequency signal filtering and signal conversion processing of a baseband signal through an improved transmitting device, and transmitting the converted baseband signal to a channel; designing a receiving device based on a Gaussian low-pass filter and a Butterworth low-pass filter, and optimizing the receiving device in combination with a Chebyshev function; sending the converted baseband signal to the receiving device by using the channel; and segmenting the frequency band of the converted baseband signal through the receiving device, and distributing the segmented frequency band to portable mobile equipment and computer equipment to complete communication. By designing the transmitting device, the tuning speed is increased; and meanwhile, the Chebyshev filter is added with a delay weight, and a metalized via hole is added on a rectangular ring of the receiving device to optimize the receiving device, so that the delay is effectively improved, and the real-time requirement is met.

Description

technical field [0001] The present invention relates to communication technology, in particular to a filter-based communication method and system. Background technique [0002] With the emergence of the digital revolution, services such as the World Wide Web, satellite broadcasting, mobile and long-distance telephones have become possible, but for modern satellite communication and land mobile communication systems, the limited frequency spectrum can no longer meet people's needs. The filter is an indispensable frequency selection device in the modern communication system, and its role is becoming more and more prominent. The performance of the filter directly affects the quality of the entire communication system. With the development of today's wireless communication technology, the performance requirements of microwave circuits are getting higher and higher, and there are more and more types, and new processes and design methods are also emerging in an endless stream. ...
