摘要
介绍了湍流信道条件下光强闪烁的对数正态分布模型,结合大气信道特点,在不同光强闪烁效应下,对比分析了几种未编码大气激光通信副载波系统的误码性能。采用Turbo码性能限分析了基于Turbo编码的无线光通信副载波调制系统误码性能,并对Turbo编码前后系统误比特性能进行了对比。仿真结果表明, 二进制相移键控(BPSK)误码性能优于其它几种副载波调制,同时Turbo码技术在较强光强闪烁指数下能够获得较大的编码增益,可以有效地提高系统的抗干扰能力。
Abstract
Optical wireless communication based on the log-normal model under the turbulence channel was introduced. Combining the characteristics of atmospheric channel, we analyzed the error rate of atmospheric laser communication using several kinds of subcarrier modulation system is analyzed. Under different scintillation distribution, the error rate of wireless optical communication using subcarrier modulation on turbo code was analyzed, and the bit error rate (BER) performance between Turbo coded and uncoded systems was compared. The simulation results showed that the error performance of binary phase shift keying (BPSK) was better than others, and turbo coded is efficient to improve jamming-rejection capability of system with the low signal-noise ratio (SNR) and strong scintillation index.
