Unconditionally Convergent pre-Distortion of non-Linear High Power Amplifiers
نویسندگان
چکیده
The use of High Power Amplifiers (HPA) in digital communications is plagued with non-linear (AM/AM and AM/PM) distortion. This is specially acute for those modulations that are not constant amplitude, such as OFDM or MQAM. We present a pre-distortion algorithm that, in contrast to previously researched architectures, is unconditionally convergent.

Effects of Non-Ideal Pre-Distorter High Power Amplifiers in WCDMA Using Multi-User Detectors
Wide band code division multiple access (WCDMA) signals, transmitted by the base station high power amplifiers (HPAs), show high peak to average power ratios (PAPR), which results in nonlinear distortions. In this paper, using computer simulations effect of using a predistorted HPA on the symbol error rate (SER) of multi-user detectors in terms of output back-off (OBO) in the transmit power...
متن کاملPerformance of MF-MSK Systems with Pre-distortion Schemes
Efficient RF power amplifiers used in third generation systems require linearization in order to reduce adjacent channel inter-modulation distortion, without sacrificing efficiency. Digital baseband predistortion is a highly cost-effective way to linearize power amplifiers (PAs). New communications services have created a demand for highly linear high power amplifiers (HPA's). Traveling Wave Tu...
متن کاملEnhanced Power Efficiency of Mobile OFDM Radio using Pre- distortion and Post-compensation
–High power efficiency is an important requirement in cellular transmitter radios. OFDM systems require very linear transmission because of high peak-to-average-power-ratio (PAPR). However, linear power amplifiers (PA) have very low efficiency. To enhance the power efficiency, non-linear PAs are applied and even forced to work near the saturation point. This generates inevitably huge non-linear...

250 Abstract—Trellis coding combined with expanded signal sets has been considered in this paper to improve error performance over uncoded modulation. New communications services have created the demand for highly linear high power amplifiers (HPA's). Traveling Wave Tubes Amplifiers (TWTA) continue to offer the best microwave HPA performance in terms of power efficiency, size and cost, but lag...
متن کاملPre-distortion Algorithms for Power Amplifiers
Future wireless networks are expected to provide ubiquitous access to high data rate services with a quality up to — and even beyond — today’s common standards for fixed-line connections. To achieve this goal, modulation schemes with a high spectral efficiency need to be utilised. However, these schemes are very susceptible to nonlinear distortions. On the other hand, the radio frequency power ...
