摘要
提出了一种MC-CDMA信号测距方案,该方案利用信号中伪随机序列的频域相关性,结合频域搜索,进行精确测距。理论分析和仿真实验表明该方案具有良好的抗噪声特性,且在存在大多普勒频偏时仍具有较好性能。
A novel ranging technique of MC-CDMA is proposed, the precise range is estimated by relativity of PN sequence in frequency domain and frequency searching. Theoretical analysis and computer simulation show that this method is robust to noise and still has superior synchronization performance when existing Doppler effect.
