Performance analysis of an MC-CDMA broadcasting system under high power amplifier non-linearities .I. System proposal

Multi-carrier modulation (MCM) schemes have been under developed as an effective way to improve channel capacity utilization under multipath interference and selective fading reception for next generation two-way wireless communication systems. However, in the application of one-way broadcasting there is a great need for a new system that cannot only operate in a multipath environment, but also can reuse scarce spectral resources and employ cost-effective high-power amplifiers. For this research, an MCM system referred to as multi-carrier code division multiple access (MC-CDMA) was developed to characterize the primary broadcasting concern of operating under high power amplifier (HPA) nonlinearities. We cover MC-CDMA background, its application to broadcasting, the expected performance limits, and modeling approach
