these peak-reducing signals are built by using spreading codes that are either dynamically selected those users that are known to be idle, or deliberately reserved a priorifor PAPR reduction purposes. The concept of adding orthogonal signals for peak

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
