| 摘 要： | 介绍了一种基于TMS320VC5402 DSP芯片的汽车防撞雷达及其信号处理系统的软硬件设计方法。该系统对车载毫米波雷达接收信号利用变步长LMS自适应算法进行噪声消除,有效地克服了固定步长因子所导致的收敛速度与稳态误差之间的矛盾,提高了处理速度。计算机仿真证实,该算法具有可行性,易于实时实现噪声对消系统。

| Abstract: | Hardware and software design of automotive collision avoidance radar based on TMS320VC5402 and its signal processing system was presented,in which variable step-size LMS algorithm cancellation was used to cancel the signal noise.It allowed for more flexibility between error adjustment and convergence time without compromise,and thus increased processing speed.Computer simulation indicated the feasibility of the algorithm,which was helpful to realize real-time noise cancellation system. |
