A Low-complexity Feed-forward I/Q Imbalance Compensation Algorithm
نویسندگان
چکیده
This paper presents a low-complexity adaptive feedforward I/Q imbalance compensation algorithm. The feed-forward solution has guaranteed stability. Due to its blind nature the algorithm is easily incorporated into an existing receiver design. The algorithm uses three estimators to obtain the necessary parameters for the I/Q imbalance compensation structure. The algorithm complexity is low due to 1-bit quantization in the estimators. Simulations show that the compensation algorithm is able to attain an image-rejection ratio (IRR) of up to 65 [dB] under various imbalance conditions.

Carrier Frequency Offset Estimation and I/Q Imbalance Compensation for OFDM Systems
Two types of radio-frequency front-end imperfections, that is, carrier frequency offset and the inphase/quadrature (I/Q) imbalance are considered for orthogonal frequency division multiplexing (OFDM) communication systems. A preamble-assisted carrier frequency estimator is proposed along with an I/Q imbalance compensation scheme. The new frequency estimator reveals the relationship between the ...
متن کاملPreamble Design for an Efficient I/Q Imbalance Compensation in OFDM Direct-Conversion Receivers
The growing number of different mobile communications standards calls for inexpensive and highly flexible receiver architectures supporting these standards. The direct-conversion receiver is a very attractive candidate for reaching this goal. However, unavoidable imbalances between the Iand the Q-branch of the I/Q demodulator lead to a significant performance degradation at the reception of OFD...
متن کاملElimination of Harmonic Force and Torque in Active Magnetic Bearing Systems with Repetitive Control and Notch Filters
Harmonic force and torque, which are caused by rotor imbalance and sensor runout, are the dominant disturbances in active magnetic bearing (AMB) systems. To eliminate the harmonic force and torque, a novel control method based on repetitive control and notch filters is proposed. Firstly, the dynamics of a four radial degrees of freedom AMB system is described, and the AMB model can be described...
متن کاملBlind I/Q Imbalance Compensation for M-QAM Optical Coherent Systems Based on Pseudo-Rotation
This paper addresses the problem of Inphase/Quadrature (I/Q) imbalance sensitivity of communication systems when it occurs at both Transmitter (TX) and Receiver (RX) sides of an optical coherent system. A novel blind technique is proposed based on the pseudo-rotation of the M-QAM constellation. The pseudo-rotation based compensator is a generic approach, because it does not depend on the modula...
متن کاملI/Q Imbalance Compensation and Channel Equalization in OFDM Receivers
IQ imbalance that is prominent in Decision-directed architecture can cause significant degradation in the performance of wireless communication systems. In this paper, a discussion of a new algorithm that uses both training and data symbols in a decision-directed fashion to jointly estimate and compensate for the effects of the channel and high receiver I/Q imbalance is presented.
