Description: 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 power mitigation has been previously proposed to reduce PAPR in Discrete MultiTone and OFDM transmissions[13,27], and also in CDMA downlink systems [28]. -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.

Description: 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 minimization problem.
The rest of the article is structured as follows: Section MC-CDMA with SFBC defines basic concepts related to SFBC MC-CDMA. Section PAPR reduction via UR describes the UR technique. Section Dimension reduction is devoted to explore the possibility of reducing the complexity of the optimization problem-However, to the authors knowledge, the implementation of this idea in the context of MIMO MC-CDMA communications has never been addressed.

Description: 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 symbols each active user are spread in the frequency domain into N = LM subcarriers, where L represents the spreading factor. This is accomplished by multiplying every symbol of the block for user k, where k ∈ {0,1,..., L - 1}, by a spreading code , -MC-CDMA with SFBC
