Multiple Access Interference Analysis in Asynchronous GSFH/MC-CDMA Systems
Xuan Li, Bouchra Senadji · 2007
Multiple access interference (MAI) is one of the main limitations of asynchronous MC-CDMA systems. The introduction of group subcarrier frequency hopping technique to MC-CDMA (GSFH/MC-CDMA) provides a possible solution for reducing the MAI effect. In this paper, we analyze the MAI performance of GSFH/MC-CDMA under asynchronous transmission. Three different detection scenarios are considered. The expression of MAI power is derived and verified using Monte-Carlo simulation results.
