Embodiment Construction
[0022] The present invention proposes a method for compressing ocean line sensor array data based on discrete cosine transform. The method converts a group of data into frequency data through discrete cosine transform before data transmission for the ocean route data collected by monitoring sensors, so as to know Intensity changes, and by quantizing and encoding the transformed array, eliminating information redundancy, effectively reducing the code length in data transmission, reducing the number of wireless transmissions, and effectively saving the transmission costs of the entire ocean route monitoring sensor network loss and energy loss.
[0023] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0024] Such as figure 1 Shown is a flow chart of a discrete cosine transform-based ocean line sensor array data...
