由于对移动的用户的高质量多媒体服务的需求，无线宽带技术在过去几年中经历了巨大的增长。MC-CDMA是OFDM与CDMA的组合;其中可以获得协同效应，诸如增强对频率选择性衰落的鲁棒性和可能的数据传输速率的高可伸缩性。本书的主要方向是通过降低峰均比来改善MC-CDMA系统。本书介绍了新的宽带技术（MC-CDMA-FDMA），它依赖于当前的4G上行链路（SC-FDMA）系统。详细阐述了SC-FDMA系统的细节和方程，其中所提出的MC-CDMA-FDMA系统被示出在低误码率和低PAPR方面具有优势。因此，MC-CDMA-FDMA技术将成为未来无线宽带技术研究的重要课题之一。
Wireless broadband technology has seen enormous growth in the last several years because of the demand for high quality multimedia services to mobile users. MC-CDMA is a combination of OFDM with CDMA; where synergistic effects can be obtained, such as enhancement of robustness against frequency selective fading and high scalability in possible data transmission rate. The main trend of this book is to improve MC-CDMA system by reducing PAPR. This book presents new broadband technology (MC-CDMA-FDMA) which depends on the current 4G uplink (SC-FDMA) system. The SC-FDMA system is elaborated with details and equations where the proposed MC-CDMA-FDMA system is shown to have advantages in terms of low bit error rate and low PAPR. Therefore MC-CDMA-FDMA technique can be one of the important topics for researchers who are looking forward for robust and high data rate wireless broadband technology.
