Propagation of Partially Coherent Beams in Atmospheric Turbulence, expansion, and beam wander will be caused, which seriously affect the performance of laser communication and tracking and imaging systems. Partially coherent beam is less affected by atmospheric turbulence, which makes its propagation characteristics become a research hotspot in recent years. In th

Progress in Research on Channel Equalization in Optical Wireless Communication, characteristics at the receiving end can offset the negative impact of the channel on the signal, so as to correct the inter-code crosstalk problem caused by multipath delay and other factors, and enable the signal to be recovered and reconstructed at the receiving end. On the basis of summarizing

Error-Correction Coding,e channel code is usually used to correct the error caused by the channel noise. Common channel codes are Reed–Solomon (RS) code, turbo code, low-density parity-check (LDPC) code, polarization code, and other types. The development of the error-correction code was combed, the research progress of th

Xizheng Ke the structures of whiteness and institutional control.DrawsThis book explores the ‘invisible‘ impact whiteness has on the lived ‘black‘ experience in the UK. Using education as a philosophical and ethical framework, the author interrogates the vision of Black Radicalism proposed by Kehinde Andrews,
