Performance analysis of an MC-CDMA broadcasting system under high power amplifier non-linearities, Part 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 can not 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, In Part I of this two-part series, we will cover MC-CDMA background, its application to broadcasting, the expected performance limits, and modeling approach, Part II, to be published in a future issue of this Transactions (in 2001) will focus on results and analysis.
