Multi-channel baseband signal filtering and coding method

The invention discloses a multi-channel baseband signal filtering and coding method, which relates to the technical field of wireless communication, and is characterized in that a multi-channel baseband signal matrix is arranged, and corresponding baseband signal element items are arranged in the multi-channel baseband signal matrix according to the number of communication channels in a communication base station and are used for storing baseband information needing to be transmitted; and according to the capacity of the baseband information and the communication resources of the communication channel, a loading response frequency range for transmitting the baseband information is obtained, so that the formulation of a signal filtering coding strategy of the baseband information is completed, and the communication channel carries out signal filtering on the baseband information needing to be transmitted according to the formulated signal filtering coding strategy. Therefore, a communication channel can formul
