OFDM+CDMA的英文PPT，写的很不错 -OFDM+ CDMA English PPT, written by very good

Several approaches to combine multicarrier modulation with code-division multiple access (CDMA) techniques have been proposed with the aim of bringing the best of both worlds to wireless communications [1]. Among these, multi-carrier CDMA (MC-CDMA),

CDMA (OFDM-CDMA), offers several key advantages such as immunity against narrowband interference and robustness in frequency-selective fading channels[2]. Such desirable properties make MC-CDMA an attractive choice for the present and future radio-co

However, to the authors knowledge, the implementation of this idea in the context of MIMO MC-CDMA communications has never been addressed. In this study, our aim is also to develop strategies to alleviate the inherent complexity of the underlying min

MC-CDMA with SFBC In the next subsections, we describe the architecture of an SFBC MIMO MC-CDMA transmitter, and define the basic terms related to the PAPR of the involved signals. System model In an MC-CDMA system, a block of M information sym
