چکیده
In this paper, multi-antenna transceiver for zero-padded orthogonal frequency division multiplexing (OFDM) system is designed at mmWave by integrating full-duplex unmanned aerial vehicle (UAV) into the terrestrial cellular networks. Assuming that there exist no direct communication links between ground base station (GBS) and mobile users due to unexpected blockages from high storied buildings in urban area, UAV applies decode-and-forward cooperative strategy on received OFDM signals transmitted GBS re-transmits passive eavesdropper. proposed system, intertwining logistic map (ILM)-cosine transform aided encryption algorithm combined with artificial noise enhancing physical layer security (PLS) introduced. Also walsh-hadamard technique integrated QR-decomposition based zero forcing (ZF) block diagonalization (QR-ZF-BD) precoding multi-user interference reduction non-iterative clipping filtering peak average power ratio (PAPR) are utilized. addition, Low density parity check (LDPC) repeat accumulate (RA) channel coding cholesky decomposition ZF minimum mean square error signal detection schemes improved bit rate (BER) also Numerical results demonstrate effectiveness of terms PLS color image transmission order digital modulation (16-PSK 16-QAM). At complementary cumulative distribution function probability level 1-6%, estimated PAPR found have value 6 dB.The three achieve BER $= 1\times {10}^{-4}$ signal-to-noise 1.5 dB, 4 dB under RA 16-QAM modulation.

Linear Transceiver Design for Bidirectional Full-Duplex MIMO OFDM Systems
In this paper we address the linear precoding and decoding design problem for a bidirectional orthogonal frequencydivision multiplexing (OFDM) communication system, between two multiple-input multiple-output (MIMO) full-duplex (FD) nodes. The effects of hardware distortion as well as the channel state information error are taken into account. In the first step, we transform the available time-d...
متن کاملEfficient Detection of Zero-padded Ofdm Signals with Large Blocks
In this paper, we present a frequency-domain receiver for ZP-OFDM schemes (Zero-Padded Orthogonal Frequency Division Multiplexing) where the duration of the channel impulse response is a significant fraction of the duration of the OFDM block. The proposed receiver has a relatively low complexity, allowing an FFT-based (Fast Fourier Transform) implementation. The proposed receiver is suitable to...
متن کاملZero padded Symmetric Conjugate Self Cancellation Technique in MB-OFDM System Design
UltraWideband (UWB) systems use Multi-Band OFDM (MB-OFDM) techniques for transmission. UWB based systems are power limited by the regulation of Federal Communications Commission (FCC). CP introduces correlation in the transmitted data sequence and hence introduces ripples in the power spectral density (PSD) of the transmitted data. This in turn reduces the range of data transmission. The overla...
متن کاملReduced complexity equalizers for zero-padded OFDM transmissions
The widespread application of OFDM for local area mobile wireless broadband systems is strongly motivated by the simple equalization it a ords. OFDM's bottleneck of channel-dependent performance was only recently addressed by replacing the cyclic pre x (CP) with trailing zeros (TZ). Such zero-padded OFDM transmissions enable FIR channel-irrespective symbol recovery which results in signi cant B...
