... any conventional MIMO detector that works for a square MIMO channel for the detection of s Q . For convenience, denote by s k Q the detected symbol vector of s Q (by any means) for given s P = s k P .Let s k = ⎡ ⎣ s P s k Q ⎤ ⎦ . ... PVC-MIMO detection, we note different postvoting vector results in different H Q which may lead to different performance of sub -detection. In order to...

... baseband and RF linearly modulated signals and identify the interesting features that can be used for signal detection. 5.1. Baseband Signals. The TCF of the baseband signal (1) has been computed in ... baseband or RF signals for α = 0 have shown that the two detectors exhibit similar performances. From now on, we will focus on the fourth- order feature detection for baseband si...
