[ 1 ] - تأثیر عدم توازنIQ برنرخ خطای بیت مدولاسیون تطبیقی در سیستم‌های MIMO

Abstract The effect of IQ imbalance on adaptive MQAM modulation in MIMO systems with direct conversion receivers is investigated in this paper. A continues power, discrete rate adaptive modulation scheme in using MIMO system with perfect channel information in both transmitter and receiver is considered. The selected adaptation mechanism changes the transmit power and transmit constellation s...
