摘要

为了提高正交频分复用（OFDM）光探测与测距（LiDAR）通信集成系统的抗干扰能力，提出了一种多输入多输出(MIMO)-OFDM激光雷达通信集成系统。该系统采用MIMO空间分集技术保证信号质量，并利用粒子群优化算法优化激光雷达资源单元（RUs）的功率分配。仿真结果表明，在$4 × 4$ MIMO配置下，与传统OFDM系统相比，该系统的误码率（BER）性能至少提高了7 dB。距离方向的峰值旁瓣比（PSLR）和综合旁瓣比（ISLR）分别降低了12.91 dB和11.92 dB。经过PSO优化后，系统在速度方向上的ISLR进一步降低了15.49 dB。

Optimization of OFDM LiDAR-Communication Integration System Using MIMO and PSO

To enhance the anti-interference capability of the orthogonal frequency division multiplexing (OFDM) light detection and ranging (LiDAR)-communication integration system, a multiple input multiple output (MIMO)-OFDM LiDAR-communication integration system is proposed. The system employs MIMO spatial diversity techniques to ensure signal quality and utilizes the particle swarm optimization (PSO) algorithm to optimize the power distribution of LiDAR resource units (RUs). Simulation results demonstrate that, in the

$4\times 4$

MIMO configuration, the proposed system achieves a minimum of 7 dB improvement in bit error rate (BER) performance compared to conventional OFDM systems. Additionally, it reduces the peak sidelobe ratio (PSLR) and integrated sidelobe ratio (ISLR) in the range direction by 12.91 dB and 11.92 dB, respectively. Following PSO optimization, the system further decreases the ISLR in the velocity direction by 15.49 dB.
