“…One can see that Doppler spread always leads to worse BER performance than the same amount of carrier frequency offset because part of interference due to the fixed carrier frequency offset has been partly canceled by differential detection at the receiver. The BER curves for the case of dual-branch diversity obtained using a Gaussian approximation method [13] are shown in the same figure.…”

“…The difficulty in evaluating the BER performance of an OFDM system in the presence of ICI lies in the fact that the exact distribution of the ICI is not known. The ICI is not Gaussian distributed, although it was approximated as a complex Gaussian random variable in [9], [10], [13]- [16]. In fact, we will show in this paper that the ICI has a probability density function (PDF) of a mixture of complex Gaussian random variables.…”

“…In fact, we will show in this paper that the ICI has a probability density function (PDF) of a mixture of complex Gaussian random variables. We then use a different method from [9], [10], [13]- [16] to derive an exact closed-form BER expression for a π/4-DQPSK OFDM system operating with diversity reception and maximal ratio combiner (MRC) in the presence of frequency offset over frequency-selective fast Rayleigh fading channels. Our exact BER expressions are obtained by noting that the received signal conditioned on data symbols is Gaussian distributed.…”

“…The BER performances of several differential modulation schemes, including MDPSK and π/4-DQPSK were examined in [13]- [16] by using Gaussian approximation methods. The difficulty in evaluating the BER performance of an OFDM system in the presence of ICI lies in the fact that the exact distribution of the ICI is not known.…”

An exact closed-form bit error rate (BER) expression is derived for an orthogonal frequency-division multiplexing system with π/4-shifted differentially encoded quadrature phase shift keying (π/4-DQPSK) in the presence of carrier frequency offset over frequency-selective fast Rayleigh fading channels. Different system configurations, including time domain differential modulation, frequency domain differential modulation, single channel reception, and multi-channel reception with maximal ratio combining diversity, are considered in the exact BER analysis. For a small number of subcarriers, the BER expression can be calculated directly. A Monte Carlo method is designed to evaluate the BER for a large number of subcarriers. The analytical expression can be used to investigate the effect of several channel parameters, including mean delay spread and maximum Doppler spread, on the system BER performance. Particularly, the effect of carrier frequency offset on the system performance, and the differences and opportunities to use frequency domain differential modulation or time domain differential modulation, can be studied in a quantitative way for a more realistic wireless channel environment model. By using the exact closed-form BER expression, an optimum number of subcarriers can be found, and the allowable carrier frequency offset, Doppler spread, and mean delay spread for given operating conditions can be determined.Index Terms-Bit error rate analysis, carrier frequency offset, frequency-selective fading, inter-carrier interference, OFDM, orthogonal frequency-division multiplexing.

In this paper we present a study of Bit Error Rate (BER), for Digital Audio Broadcasting (DAB) system, employing Coded OFDM with different channel coding schemes. Analysis is carried out for convolutional coded and turbo coded data in an Additive White Gaussian Channel (AWGN) based on different constraint lengths and code generator polynomials used for coding. A comparative study on the computational complexity is also done by applying an audio signal and measuring the data processing time per frame, on computers with different processor speeds. It is shown that a coding gain of approximately 6 dB is achieved using turbo coding when compared to convolutional coding, at a cost of higher computational complexity.

After more than two decades since intensive research began on power line communications (PLC) technology, this interesting field of telecommunication engineering is still progressing towards maturity. Despite some factors that delay its worldwide acceptance, its implementation is starting to take off. Research in PLC is motivated (i) by many factors such as the crowded radio frequency spectrum that requires to be sustained by alternative technologies and (ii) by the emanation of other new technologies that may help PLC to extend its practical implementation such as visible light communications or other wireless communication technologies like near‐field communications. PLC technology is used in applications requiring both low and high data rate but traditionally exploited in applications in which the node does not move. Nowadays, PLC has become widely accepted; hence, a review of the technology may be useful to keep the readers aware of new updates. In this paper, we provide an overview of the evolution of PLC technology over the last few decades.
