Abstract(in English) | This paper proposes a novel method which suppress multi-access interference in DS, SSMA for the near-far problem.When the duration of the cross correlation function,which causes multi- access interference,is divided into several intervals,the partial cross correlation function has different value according to each interval.So that,improvement of signal to noise ratio after dump integrator of correlator can be obtained by multiplying small weight coefficients with large values of the partial cross correlation functions,and multiplying large weight coefficients with small values of the cross correlation functions. Using this proposed method,suppression effect of multi-access interference can be obtained without knowing the PN sequences of other users in random accessing The characteristics of this system and results of computer simulations are shown in this paper. |
