Abstract-This article proposes an efficient design and implementation of Framelet-Based Orthogonal Frequency Division Multiplexing (OFDM) with Finite Radon Transform (FRAT), named as (FRAT-FT-OFDM), on Field ProgrammableGate Array (FPGA) platform. Modern FPGA design tool called Xilinx System Generator (XSG) is used to implement the transceiver of FRAT-FT-OFDM system. The FPGA implementation is carried out on a Zynq (XC7Z020-1CLG484) evaluation board with Joint Test Action Group (JTAG) hardware co-simulation. Performance of the implemented architecture has been validated through hardware co-simulation in term of utilized area and consumed power. The results showed that the system was implemented efficiently with few resources and consumed power, and could support realtime operations.Keyword -OFDM, Framelet Transform, Radon Transform, FPGA, Xilinx System Generator I. INTRODUCTION Orthogonal Frequency Division Multiplexing (OFDM) is a special case of multicarrier transmission technique for achieving high data rate transmission over multipath fading channel. It has been widely applied in many wireless and mobile networks especially for the communication standards [1]. In conventional OFDM system, Inverse Fast Fourier Transform (IFFT) is used at transmitter side and Fast Fourier Transform (FFT) is used at receiver side to generate orthogonal subcarriers [2]. The derivation of the system model also shows that by introducing a Cyclic Prefix (CP), the orthogonality can be maintained over a dispersive channel and the Inter-Symbol Interference (ISI) can be avoided but this come at the cost of decreasing the transmission efficiency and increasing complexity of the system [3].OFDM based on wavelet transforms were also proposed by a number of researchers [4][5][6][7]. The idea of using wavelet transform instead of Fourier transform, because of its high spectral containment properties compared with Fourier transform. Among these, Framelet transform-based OFDM (FT-OFDM) [6] was shown to have better Bit Error Rate (BER) performance than Discrete Wavelet Transform (DWT)-based OFDM and FFTbased OFDM. However, FT-OFDM is unsuitable for outdoor wireless applications, where data must be transmitted at high rates with Doppler spread robustness. Therefore, Hadi et al. [8] improved the performance of FT-OFDM system by using Finite Radon Transform (FRAT) as a mapping technique and combined it with FT to produce a new model called as FRAT-FT-OFDM system. In this system, Radon transform was used as a mapping technique instead of conventional mapping techniques such as Quadrature Amplitude Mapping (QAM), and the FT was used to realize the multicarrier modulation instead of FFT or DWT.For the time being, hardware realization of OFDM system using Field Programmable Gate Array (FPGA) is an important area of research due to the speed of implementation, low development costs and less time to market with the ability to reduce the complexity and power consumption without sacrificing in the performance of the system [9].

Watermarking is a tool of confidentiality that protects valuable information hidden in the set of digital media by modifying the particular graphic contents. Special purpose hardware designed systems can be mapped in watermarking through FPGA. In this paper, the process of watermarking is performed on image using Xilinx system generator. Watermarking is performed in DWT domain using MATLAB after scaling of watermark data in Simulink environment. The co-hardware simulation has been performed for developed model using VIRTEX 6, ML605 BOARD to see the capability of watermarking system. The Simulink and system Generator through FPGA model extracts the Watermark appropriately and thereafter device utility for embedding system is determined.

In this paper we propose a novel and efficient hardware implementation of an image watermarking system based on the Haar Discrete Wavelet Transform (DWT). DWT is used in image watermarking to hide secret pieces of information into a digital content with a good robustness. The main advantage of Haar DWT is the frequencies separation into four subbands (LL, LH, HL, and HH) which can be treated independently. This permits ensuring a better compromise between robustness and visibility factors. A Field Programmable Gate Array (FPGA) that is based on a very large scale integration architecture of the watermarking algorithm is developed to accelerate media authentication. A hardware cosimulation strategy using the Matlab-Xilinx system generator (XSG) was applied to prove the validity of the suggested implementation. The hardware cosimulation results show the effectiveness of the developed architecture in terms of visibility and robustness against several attacks. The proposed hardware system presents also a high performance in terms of the operating speed.
