弱湍流下斜程大气激光通信误码率分析
BER performance analysis of the atmospheric laser communication system on the slant path in weak turbulence
摘要
Abstract
Based on the three-layer altitude spectrum , this paper analytically investigates the bit error rate (BER) performance of the slanted laser communication system under the weak turbulence condition . The expressions for BER using on-off keying ( OOK ) and pulse position modulation ( PPM ) are derived . An analysis of impacts of the zenith angle , wavelength , power-law index and modulations on BER is made . Theoretical results show that the descriptions of turbulence given by the three-layer altitude spectrum is consistent with the actual situation . With the wavelength decreasing and zenith angle increasing , BER increases . Furthermore , PPM requires less average transmitted power than OOK , which may achieve the aim of saving cost without increasing the error rate in system design .关键词
