Two forms of flower-like ZnO nanostructures were synthesized using hydrothermal methods at various growth times/temperatures and zinc precursors. The morphology, structure, chemical composition, and optical properties of these ZnO nanoflowers were st

Multiple input, multiples output (MIMO)-constant envelop modulation (CEM), has been proposed to be an efficient power alternative transceiver system to MIMO-OFDM. To attain a high power efficient MIMO transceiver, MIMO-CEM uses a constant envelope mo

In this paper, a low complexity MIMO detection is proposed for MIMO-Constant Envelope Modulation (MIMO-CEM) transceiver system. In which, an adaptive sphere decoder (SD) based on an affine linear transformation model is proposed to adaptively select
