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

Description: In this paper, we investigate blind channel estimation for Multiple Input Multiple Output (MIMO) multi-carrier
CDMA (MC-CDMA) systems in the uplink scenario. An Autocorrelation Contribution Matrix (ACM) method is proposed in
comparison with the subspace approach. Using only second order
statistics, the ACM approach shows similar performance to that
of subspace based approach. The added advantage is that it eliminates the need for rank estimation and noise power calculation
as in subspace technique. In particular we incorporate blind
channel estimation with Layered Space Frequency Equalisation
(LSFE),which employs successive interference cancellation and
therefore provides significant performance improvement over the
conventional linear minimum mean square error (MMSE) based
approach.
