| Popis: | Advanced Driver Assistance System (ADAS) detects the road conditions using sensor such as ultrasonic sensor. In this paper, obstacle detection function of ultrasonic sensor is simulated in interference environment for ADAS. Using DQPSK modulation, ID transmission and non-coherent receiver implemented. After, this matched filter yields correlation of two waves, reflected wave and binary sequence including ID. This shows that position of peak on correlation plot correspond receiving time of reflected wave. |
