2007 journal article

Estimation of co-channel nonlinear distortion and SNDR in wireless systems

IET MICROWAVES ANTENNAS & PROPAGATION, 1(5), 1078–1085.

By: K. Gharaibeh*, K. Gard n & M. Steer n

TL;DR: The analysis is based on the orthogonalisation of the nonlinear behavioual model that allows the accurate estimation of the effective in-band (or co-channel) distortion and hence determination of SNDR. (via Semantic Scholar)

2005 journal article

Modeling distortion in multichannel communication systems

IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES, 53(5), 1682–1692.

By: K. Gharaibeh n & M. Steer n

author keywords: behavioral modeling code division multiple access (CDMA); cross-modulation distortion; multichannel; nonlinear systems; power amplifiers; statistical modeling
TL;DR: A behavioral modeling technique suited to capturing the response of wide-band multifunctional and multichannel amplifiers is introduced, based on the three-box approximation of the Volterra model, which enables accurate estimation of intermodulation and cross-modulation distortions of multiple digitally modulated signals.

2003 article

Characterization of cross modulation in multichannel amplifiers using a statistically based behavioral modeling technique

Gharaibeh, K. M., & Steer, M. B. (2003, December). IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES, Vol. 51, pp. 2434–2444.

By: K. Gharaibeh n & M. Steer n

author keywords: behavioral modeling; code division multiple access (CDMA); cross-modulation distortion; multichannel; nonlinear systems; power amplifiers; statistical modeling
TL;DR: A statistically based modeling technique is developed for characterizing in-band and out-of-band intermodulation and cross-modulation distortions in multichannel amplifier environments using a new multiple envelope memoryless behavioral model that captures the black-box characteristics of multich channel amplifiers.
