4x4mimo
A 2x2 multiple-input multiple-output (MIMO) architecture
using dual-polarized antennas (DPAs) is considered
with orthogonal frequency division multiplexing (OFDM). The
performance of DPAs is evaluated for adaptive polarization
(AP) transmission techniques in time-varying multipath channels
impaired by polarization mode dispersion (PMD) and
polarization-dependent loss (PDL). AP transmission techniques
considered include power gain maximization, polarization dispersion
minimization for interference avoidance, polarization
multiplexing with waterfilling, and a suboptimal multiplexing
strategy that enables direct recovery of the polarization multiplexed
streams, thereby simplifying the design of the receiver.
Measured time-varying dual-polarized channel realizations from
mobile-to-mobile experiments are used to estimate the capacity,
diversity, and interference avoidance performance of the adaptive
approaches.

Abstract—In this paper, we study the joint estimation of inphase
and quadrature-phase (I/Q) imbalance, carrier frequency
offset (CFO), and channel response for multiple-input multipleoutput
(MIMO) orthogonal frequency division multiplexing
(OFDM) systems using training sequences. A new concept called
channel residual energy (CRE) is introduced. We show that by
minimizing the CRE, we can jointly estimate the I/Q imbalance
and CFO without knowing the channel response. The proposed
method needs only one OFDM block for training and the training
symbols can be arbitrary. Moreover when the training block
consists of two repeated sequences, a low complexity two-step
approach is proposed to solve the joint estimation problem.
Simulation results show that the mean-squared error (MSE) of
the proposed method is close to the Cramer-Rao bound (CRB).
Index Terms—MIMO OFDM, CFO, I/Q imbalance, channel
estimation.
