【Abstract】 In order to investigate the performance of power allocation for spatially coupling data transmission,under conditions in which the interference of among coupling data streams is eliminated completely,the author proved that the system performance can achieve optimal for equal power transmission by utilizing density evolution and potential function.To reduce higher detection complexity caused by equal power transmission at the price of a small performance loss,a new power allocation algorithm was proposed to implement unequal power transmission.Extrinsic information transfer chart analyses and simulation results verify the correctness of theory analysis and the feasibility of the proposed algorithm.更多还原
