I am a new developer in DSP board I am currently working on a project to measure the speed of a small car via Cross correlation in DSP board. This small car has embedded two infrared light sensors which send and receive random signals from the floor. Two random signal are similar except the time delay when the floor reflects the signals. The sensor signals are transmitted to the wireless sender and received by the wireless receiver. The wireless receiver is connected to the DSP board so that the cross correlation Algorithms can be implemented. My question is if there is any article related to the time delay estimation via cross correlation and there is anyone who has experience programming a cross correlation in the DSP board. Thanks in advance
