The sensitivity of channel bit error rate (BER) to the turbo coding parameters (i.e., code rate, iterative number and interleave length, etc) and the wireless channel statistic enlightens us to model a BER for turbo coding over Rayleigh channel. The model presented in this paper synthetically considers and quantificationally analyzes the impacts of all the coding parameters and the wireless cha...

DNA constantly undergoes chemical modification due to endogenous and exogenous mutagens. The DNA base excision repair (BER) pathway is the frontline mechanism handling the majority of these lesions, and primarily involves a DNA incision and subsequent resealing step. It is imperative that these processes are extremely well-coordinated as unrepaired DNA single strand breaks (SSBs) can be convert...

The performance of single-carrier (SC) transmission in a frequency-selective fading channel degrades due to a severe inter-symbol interference (ISI). Using frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can improve the bit error rate (BER) performance of SC transmission. However, the residual ISI after FDE limits the performance improvement. In this ...

Multi-carrier code division multiple access (MCCDMA) is method for high speed data rate communication. It skip the problem of inter symbol interference.MC-CDMA too provide spatial diversity, which mitigate the fading. The usage of MC-CDMA can significantly improve the performance of wireless communication system. This paper presents the simulation of MC-CDMA system performance with MSK modulati...

Candida albicans causes superficial to systemic infections in immuno-compromised individuals. The concomitant use of fungistatic drugs and the lack of cidal drugs frequently result in strains that could withstand commonly used antifungals, and display multidrug resistance (MDR). In search of novel fungicidals, in this study, we have explored a plant alkaloid berberine (BER) for its antifungal p...

Using a newly established HTLV-1 positive T cell line as an immunogen, a new monoclonal antibody, Ber-ACT8, was produced. It reacts with in vitro activated T cells and a small subset of normal resting T cells, but not with resting B cells or any of the 29 established human permanent cell lines tested. Immunohistological analysis of a wide spectrum of human tissues showed that Ber-ACT8 reactivit...

A novel method of estimating the BER performance of finite length turbo codes in a binary AWGN channel is proposed. We consider the asymptotes of BER performance at low and high Eb N0 resulted from the small and large extrinsic values, respectively. The BER performance curve transitions between two asymptotes in the waterfall region, where the transition probability is approximately obtained by...

1,2 Department of Electronics and Communication Engineering, Amity University, Lucknow (India) ABSTRACT Underwater Wireless Optical Communications is an arrivingexplanation to extend the demand for broadband links in oceans and seas. In this paper we examinethe Bit Error Rate (BER)attainment of multiple-input multiple-output of Underwater Wireless Optical Communication system (MIMO-UWOC). By us...

In this paper, Performance evaluation of Free Space Optical Communication Link with Different Parameters has been observed. It has been observed that BER of received data increases when path length is increases, also increase when data rate increases. In other case it observed that BER of received data increases when path length is increases, also increase when divergence angle increases and Q ...
