On The Performance Of Interference Subspace Rejection For Next Generation Multicarrier Cdma |
Abstract | ||
---|---|---|
A multicarrier-CDMA receiver with full interference suppression capabilities, named multi-carrier interference subspace rejection (MC-ISR), has recently been proposed and assessed by simulations for high-rate transmissions over next-generation CDMA systems. In this paper, we derive a link/system-level performance analysis of MC-ISR based on the Gaussian assumption (GA) and validate it by simulations. In addition, we provide a comparative study of the two potential next-generation multicarrier CDMA air-interface configurations: MT-CDMA and MC-DS-CDMA. Simulations show that for both DBPSK and DQPSK modulations, MT-CDMA has the best linklevel performance and the highest throughput. With two receiving antennas and nine MT-CDMA subcarriers in 5 MHz bandwidth, MC-ISR provides about 1.4 bps/Hz at low mobility for DBPSK, i.e., an increase of 170% in spectrum efficiency over a DS-CDMA system with MRC. |
