Least L/sub p/-norm interference suppression for DS/CDMA systems in non-Gaussian impulsive channels
Seo-Young Lee, Julie A. Dickerson · 2003
Interference suppression using the minimum dispersion (MD) criterion has good near-far resistance for direct-sequence code-division multiple-access (DS/CDMA) systems in the presence of additive non-Gaussian impulsive noise modeled as a symmetric alpha-stable (S/spl alpha/S) process. This paper applies least L/sub p/-norm (LP) interference suppression to DS/CDMA systems in a S/spl alpha/S non-Gaussian impulsive noise channel. Simulation results show that the LP interference suppression scheme increases the system capacity and BER performance at the cost of higher computational complexity. The proposed detector has superior near-far resistance to the adaptive MD detector.
