This paper proposes and discusses two software implementations of the DVB-T modulator, using C++ and MATLAB, respectively. All the key features of the DVB-T standard are included. The C++ DVB-T modulator, incorporated into ...

Inter-carrier interference and multiple access interference due to carrier frequency offset (CFO) are two major factors that deteriorate the performance of orthogonal frequency division multiple access (OFDMA) and multicarrier ...

We propose an improved capacity lower bound for OFDM system with compressed sensing channel estimation for Bernoulli-Gaussian channel. We improve the known capacity lower bound which is based on Lasso compressed sensing ...

In this study the impact of a Radio-over-Fiber (RoF) subsystem on the performance of Orthogonal Frequency Division Multiplexing (OFDM) system is evaluated. The study investigates the use of Multi-Layered Perceptron (MLP) ...

This paper presents the design and analysis of the OFDM modulator for Digital Radio Mondiale (DRM) standard. Attention is paid to the digital signal processing in FPGA devices. The system performs carrier modulation of the ...

This paper analyzes the usability of peak to average power ratio (PAPR) reduction in multicarrier code division multiple access (MC-CDMA) by the chip interleaving optimization. This means chip position formatting to PAPR ...

Carrier frequency offset (CFO) in orthogonal frequency division multiplexing (OFDM) systems is a major problem in achieving orthogonality between subcarriers. In this paper, we propose an estimator for CFO in OFDM systems ...

It has recently been observed that the combination of the OFDM (Orthogonal Frequency Division Multiplex) and the CDMA (Code Division Multiple Access) can achieve notably lower BER (Bit Error Rate) performance in comparison ...

In this paper we proposed a smart interference rejection filter in TH-PPM UWB system, which improves the system\'s error probability for an order of magnitude in case of high power OFDM interference. The smart filter is ...

Generally OFDM systems use a predefined signal pattern, called preamble [2] [3], which helps the receiver to achieve a better signal detection (coarse, fine time synchronization) with the frequency offset and channel ...
