“…Previously in [7] we presented an asymptotic analysis for single-user multi-signature MC-CDMA. We generalized those results in [8] to multi-user multi-signature MC-CDMA with unequal powers, but limited to the case where all users had an equal number of signatures. In this paper, we consider the most general case where there is no restriction on the allocation of signatures among users.…”

In this paper we present an asymptotic analysis of a multi-signature Multi-Carrier CDMA communications system. Such a system is suited to scalable data rate services with decentralized control. Specifically, we derive the asymptotic SINR at the output of a multiuser Linear Minimum Mean Squared Error (LMMSE) receiver and the asymptotic sum spectral efficiency of both the LMMSE and optimal receivers. Simulation studies demonstrate that the asymptotic results closely predict the performance of practical finite systems.

“…We have analyzed the performance of MC-CDMA in the presence of frequency-selective Rayleigh fading with multiple users, and multiple signatures per user in [11,26,28,32]. Our results apply in the large system limit as signatures and processing tend to infinity with fixed ratio, and enable the computation of performance measures as a function of system parameters such as data rates per user, noise level, and number of users.…”
