Research of optimal detection order in DS-CDMA systems with nonlinear successive interference cancellation
|
Abstract:
In DS-CDMA systems with successive interference cancellation(SIC),different detection orders result in different system performance.This paper studied how to adjust the detection order to minimize the total transmission power in this kind of systems.Unlike existing work,considered the receiver of imperfect nonlinear SIC and supposed that the other cell interference was no longer independent of users' transmission(received) power.Under these presuppositions,derived the optimal detection order to minimize the...
