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.

说明： 自己用的小软件，仿造原子的XCOM功能，加了一下自己用的功能。
1、基本串口通讯，鼠标放入串口选择自动刷新，显示COM口的驱动类型。
2、多条发送界面，可定时发送，可关联数字键盘、右键发送按钮可更改按钮名称，方便记忆。
3、485通讯，数据有十进制和十六进制可选，发送后自动保留记录。
4、CRC校验小工具。
5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制
6、字符格式示波器，例：">P:-1.25"，示波器显示曲线名称P，数值-1.25，曲线个数最多8个。
7、类似MODBUS协议截取第2-5位，合成一个int数值，然后示波器显示波形，最多5个曲线
8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)

ModbusPollCS
某智能设备公司开关量采集系统（Modbus RTU），很不错哦！对于该类设备基本上都可以通用，只是“寄存器地址”不一样。我就参照该源程序写了一款SOS应急呼叫系统、酒店客房插卡取电、退房呼叫系统等。保证原创，独一无二。(A smart device switch acquisition system (Modbus RTU), very good, oh! Can be generic, such equipment is basically just not the same register address. I refer to the source Admission card, write a SOS emergency call system, hotel rooms, check out the call system. Guaranteed original, unique.)

A spectrum sharing method based on ATM
In recent years, the number of portable mobile terminal users is increasing with improvement of the wireless communication environment. In addition, mobile multimedia services also bring the increase of wireless traffic and lack of
spectrum resources. As a technique for efficient spectrum use, spectrum sharing receives much attention. It dynamically assigns a spectrum channel from a larger area network such as WiMAX to smaller area networks such as WiFi-based wireless LANs and achieves to increase the total wireless communication capacity of this area. In a case where all providers are cooperative, the spectrum sharing can be realized easily and improve user throughput in average. In another case where providers are not
cooperative, some spectrum trading methods based on auction theory had been proposed.
