In Section 2, the main theory of Alamouti STBC
MIMO-OFDM system, as well as the definition of PAPR are explained, and the SLM scheme is also described in this section.
For randomly generated QPSK symbols, both CCDF graphs of original and optimized signals have been illustrated, and space time block coding (STBC
) is used in order to diminish the computational complexity at the receiver side and achieve more diversity gain at the transmit side, where the test starts with two transmit antennas-based Alamouti scheme  (2 x 1) and finished by using four transmit antennas (4 x 1) [24, 25].
Total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), urea nitrogen (BUN), serum creatinine (Cr), uric acid (UA), fasting plasma glucose (FPG), serum total bilirubin concentration (STBC
), and urine microalbumin were measured on an ADVIA 2400 automatic biochemical analyzer (SIEMENS, Germany).
Therefore, combined with the STBC
coding of MIMO system, the proposed ENN depth modulation pattern recognition network can obtain high PCC.
The data is then fed to FFT and decoding of STBC
is achieved by applying MRC.
The classifier designed for space time block codes (STBC
) system using multidimensional independent component analysis (ICA) is proposed in .
Space time trellis code (STTC) and space time block code (STBC
) are the two main types of STC techniques.
Based on the LEACH clustering protocol in WSNs, a distributed virtual MIMO multihop cooperative communication protocol with STBC
encoding has been proposed in .
Advanced beamforming, Low-Density Parity Check (LDPC) code and SpaceTime Block Code (STBC
) support for better coverage and more reliable connectivity.
In the physical layer, 802.11n uses a MIMO technology where multiple antenna elements can be combined to achieve either higher PHY data rates (in Spatial Division Multiplexing (SDM) mode) or higher range (in Space Time Block Coding (STBC
