The information-combination mapping is mainly investigated based on a parallel combinatory DS/SS communication system.It’s shown that the effect of this mapping on the system is not negligible and.an easily operated method called"graph matching″to get the suboptimal mapping is presented.Computer simulation results demonstrate that it’s important to optimize the mapping
and the mapping determined with the proposed method is good enough.By a comparison of several DS/SS communication schemes
it can be found that this parallel combinatory DS/SS communication system has higher efficiency and lower complexity relatively.
