Abstract: In this paper one way is proposed to construct asymptotic and non-asymptotic confidence regions in the problem of closed loop model validation deeply. These two asymptotic and non-asymptotic confidence regions correspond to the infinite and finite data points. Firstly one asymptotic confidence region is derived from some statistical properties on noise. The uncertainties bound of the model parameter is constructed in the probability sense by using the inner product form of the asymptotic covariance matrix, then a new technique for estimating bias and variance contributions to the model error is suggested. Secondly we modify sign perturbed sums (SPS) method to construct non-asymptotic confidence regions under a finite number of data points, where some modifications are studied for closed loop system. Finally the simulation example results confirm the identification theoretical results.

Abstract: In this paper, we propose a method to reduce the peak to average power ratio in filter bank multicarrier systems. The proposed method is based on shuffling the sub-carriers in filter bank multicarrier system randomly, then, Using the PN-sequences to shuffle the sub-carriers. The simulation results confirmed the effectiveness of the proposed method and gave observed enhancement.

Abstract: Non-contiguous orthogonal frequency division multiplexing (NC-OFDM) has been considered as an outstanding technique for high data rate 5G and beyond 5G wireless communications. In this paper, we have made comprehensive performance evaluative study for a single user NC-OFDM scheme implemented wireless communication system under consideration of millimeter-wave (mmWave) large MIMO antenna configuration. In our 32×256 uniform linear antenna (ULA) configured simulated system under investigation, three selective modern channel coding (LDPC, Repeat and Accumulate and (3, 2) SPC) with a single higher order digital modulation (256-QAM)) and three signal detection (ZF, MMSE and LR-based linear detection) techniques have been utilized. On consideration of color image transmission in AWGN and Rayleigh fading channel, it is observable from MATLAB based simulation study that the Repeat and Accumulate channel encoded simulated system is very much robust and effective in retrieving color image under utilization of MMSE signal detection technique.
