However, UPA schemes are usually designed without taking into account the High Power Amplifier (HPA) nonlinearity, especially in MIMO-OFDM systems which are known to generate signals with a high Peak-to-Average Power Ratio (PAPR). This paper aims to evaluate the impact of HPA nonlinearity on the transmission of scalable image cotents over a precoded Closed-Loop MIMO-OFDM system when the well-known Content-Based Precoder (CBP) is used for UPA. For PAPR reduction, we have considered the Tone Reservation Using Null Subcarriers (TRNS) technique. Simulations are performed under the IEEE 802.11n standard in a realistic urban environment in presence of a commercial 2W class-AB memoryless HPA from RF Micro Devices. The experimental results in terms of Bit Error Rate (BER) and visual quality show that the error-protection of the most sensitive parts of the codestream against channel distortions achieved using UPA is significantly disturbed in presence of HPA nonlinearity. These results highlight the influence of HPA nonlinearity on the scalable image transmission.","PeriodicalId":205556,"journal":{"name":"2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS)","volume":"106 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133169761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that this new technique, based on the inclusion of the Guard Interval (GI) signal into the well-known Tone Reservation using Null-Subcarriers (TRNS) technique can significantly increase the PAPR reduction gain. In this paper, we propose to extend the performance evaluation of the HTR technique over Additive White Gaussian Noise (AWGN) channels in presence of a RF Power Amplifier (PA) model with memory effects. Simulation were carried out under the IEEE 802.11a standard in presence of a commercial 2W class-AB PA from RF Micro Devices. The model parameters of the considered PA were estimated by an experimental based method. The evaluation results in terms of Bit Error Rate (BER), Error Vector Magnitude (EVM) an spectral regrowth show that this new technique allows using the PA at high output level and consequently high power efficiency, while maintaining a good transmission quality compared to the classical TRNS method. These results highlight the performances of this technique in presence of PA nonlinearity.","PeriodicalId":205556,"journal":{"name":"2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134336285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Equally important, body sensors are more and more used in the medical, sports and space research fields. For instance, the breathing and heart rate signals fluctuate in the 0.5 to 5 Hz frequency range while several of the common biophysiological signals are situated between the 0.1 to 1 kHz spectrum like the electrooculography (EOG), the electroencephalography (EEG), the electrocardiogram (ECG), the electromyography (EMG). In this paper, an active low-pass filter using very high linear pseudo-resistors is presented. The pseudo-resistors allow the realization of very large resistances using small silicon area. More importantly, our proposed linearization technique provides tunable pseudo-resistors with very high linearity measured thanks to the total harmonic distortion (THD) of the output signal. Simulations results show that the proposed circuit's cutoff frequency is tunable in a wide range from 34 Hz to 20 kHz. In other words, we we were able to achieve a resistance value as high as 0.46 GO for a THD of −60 dB or 0.1%. Comparatively, for a cutoff frequency of 141 Hz and equivalent resistance of 0.11 GO, our filter achieves a THD as high as −83 dB or 0.007%.","PeriodicalId":205556,"journal":{"name":"2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124974781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
