Analysis and anti-jamming performance of partial band for IDMA systems

Abstract

IDMA can be regarded as a special case of CDMA, where the spreading can be done by an arbitrary low rate channel code equal for all users and the separation can be done by user-specific interleavers. In this paper, we provide the anti-jamming performance analysis of partial band for IDMA systems. First, we investigate the basic principle of IDMA briefly. Then introduce the generation of the partial band jamming model and the cancellation of the partial band jamming in IDMA systems. The theoretical analysis and simulation results show that the iteration, spreading gain, the number of users, and the power of jamming will affect the performance of IDMA systems. Especially, the power of partial band jamming is the maximum impact factors for IDMA systems in the circumstances of partial band jamming.
