Blind Recognition of Space-Time Block Code in MISO System
Blind recognition of Space-Time Block Codes (STBCs) used in multiple transmitter communication is an important research topic in the non-cooperative scenario, which has attracted more and more attention recently. However, all of the current recognition algorithms can only work well in multiple-input multiple-output system, i.e., the system employs multiple receive antennas. To the authors' knowledge, there is no report in the literature on blind recognition of STBCs in Multiple-Input Single-Output (MISO) system, i.e., the system employs only one receive antenna. In this paper, this matter is addressed. An original method of feature extraction for STBCs in the MISO system is proposed using the second-order and higher-order statistics of the reconstructed receiver.
