| Abstract: | Turbo product code(TPC) is introduced into free space optical communication(FSO) system to mitigate impact of random and long deep fade caused by atmospheric turbulence.After FSO system model is set up,the anti-burst error ability of TPC is studied.Also the algorithm of bit confidence measurement under weak turbulence and Gaussian cascaded channel is derived.The performances of TPC under weak turbulence and influential factors are analyzed.Simulations show that,TPC compensates the losses of random and deep ... |
