Witryna1 lis 2024 · In this paper, a generalized expression for the post-detection Signal to Noise Ratio (SNR) of the substream is derived by accounting the spatial correlation and channel estimation error. Further the Average Bit Error Rate (ABER) of ZF receiver for M-Phase Shift Keying (PSK) and M-Quadrature Amplitude Modulation (QAM) is … Witryna23 sty 2024 · Imperfect channel state information (CSI) may seriously worsen the system performance for classical MIMO communications. In order to overcome the impacts of imperfect CSI for Internet of things, we propose a deep convolutional neural network (DCNN) based MIMO detection algorithm, where the DCNN is trained offline …
