Abstract: A radar data processing method is provided. The method includes dividing to-be-compressed radar data into groups, determining encoding parameters of each group according to at least one radar data in each group, and encoding each radar data in each group according to the encoding parameters of each group, to obtain encoded radar data.

Abstract: A computer-implemented method includes receiving a feedback message from a receiver of image data. The feedback message includes a reference frame identifier associated with a reference frame correctly received or decoded by the receiver. The method further includes determining a difference between the reference frame identifier and a current frame identifier. The current frame identifier is associated with a current frame to be encoded and the difference indicates a number of frames between the reference frame and the current frame. The method also includes encoding the current frame based at least in part on the difference.

Abstract: A system for supporting data processing and communication in a movable platform environment includes a memory buffer with a plurality of buffer blocks each configured to store one or more data frames, and a plurality of data processors including at least a first data processor and a second data processor. The first data processor operates to perform a write operation to write data into one of the buffer blocks in the memory buffer and provide a reference to the second data processor via a connection between the first data processor and the second data processor. The reference indicates a status or progress of the write operation performed by the first data processor. The second data processor operates to perform a read operation to read the data from the one of the buffer blocks in the memory buffer based on the reference.
