Abstract
Adaptive differential quantization for ranging sensors and sensor data encoding is enclosed. The proposed disclosure comprises a differential quantization algorithm that extracts the raw signal data gradients to maximize the amount of effective information (using information theory approaches) transferred to a sensor processing data unit. This approach results in an efficient use of the data links between the sensor suite and a central sensor processing data engine, which can allow the use of cost-effective physical links. The proposed disclosure takes advantage of the gradual environment changes observed in typical vehicular platform trajectories.
