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.

LDPC校验矩阵生成、高斯消去法编码、BP译码程序，可以作为自己编写LDPC编译码程序的参考。因为matlab代码效率不高，所以这个程序仿真起来比较慢.(LDPC check matrix generation, Gaussian elimination coding, BP decoding procedure can be used as its own procedures for the preparation of LDPC codec reference. Because matlab code efficiency is not high, so this process is relatively slow simulation together.)
