Bit Error Rate Reduction of Dwt Based Ofdm Systems
--In OFDM systems, Fast Fourier transform (FFT) is used for frequency translation, and recently Discrete Wavelet Transform (DWT) has replaced FFT for frequency translation. 16-QAM (Quadrature amplitude modulation) scheme has been used in the OFDM system for both DWT and FFT based models. This work presents a modified OFDM system that is based on a low complexity interleaving process which is ap...
متن کاملA Simplified Model of Bit Error Rate Calculation
The Bit Error Rate (BER) is a key parameter of the Quality of Service (QoS) for engineers and designers of digital communication systems and networks. At the present time, a set of models and methods are exist for calculating the BER. But these methods are complex and require large computing cost. In this paper, we provide a new model for calculating the BER. This model simplifies the procedure...
متن کاملBit Error Rate Calculation for OFDM with Synchronization Errors in Time and Frequency Selective Fading Channels
In this paper we present an analytical approach to evaluate the bit error rate (BER) of OFDM systems subject to carrier frequency offset (CFO) and channel estimation error in Rayleigh flat fading as well as in time and frequency selective fading channels. Based on correct modeling of the correlation between channel estimates and received signals with carrier frequency offset, the bit error rate...
متن کاملNon-Linear Distortion and OFDM Bit Error Rate
Non-linear distortion of OFDM signals can significantly increase the receiver BER. Currently, distortion analyses rely on simulation, not yielding insight into the problem, or apply to specific non-linearities only. In this paper, general analytic results are presented on the errors resulting from distortion. The results are applicable to smooth non-linear distortion of an OFDM signal, which is...
متن کاملEffect of Clipping Ratio on Bit Error Rate Performance of Clipped and Filtered OFDM Signal
Wireless communications is regarded as the most important development with wide range of applications. Advances and development in this field aim for fast and reliable communication. Orthogonal frequency division multiplexing signal provides high spectral efficiency and ease of implementation. But it suffers from high peak to average power ratio. This paper presents the effect of clipping ratio...
