调整iq幅度不平衡的模块，可以解决载漏和边带问题。(Iq amplitude imbalance adjustment module can be resolved carrier and sideband leakage problems.)

数字下变频（DDC）在如今基于软件无线电的架构中对系统的整体性能决定性的影响，代码为基于Matlab的4通道DDC程序，程序中可以根据需要调节滤波器等参数评估DDC的性能对于使用FPGA实现DDC有较大的参考价值(Digital down conversion (DDC) in today' s architecture based on software radio system a decisive impact on the overall performance of the code for the 4-channel DDC Matlab-based program, the program can be adjusted according to filter parameters such as the use of performance assessment FPGA DDC DDC has achieved great reference value)

Use of Kalman and EKF on two-phase permanent magnet synchronous motor of the state estimate CDCDCDCDCCC

本程序主要是实现xinlinx fpga与dsp之间的双工通信(This program is to achieve duplex communication between xilinx fpga and dsp)

Simple UART for FPGA is UART (Universal Asynchronous Receiver & Transmitter) controller for serial communication with an FPGA. The UART controller was implemented using VHDL 93 and is applicable to any FPGA. Simple UART for FPGA requires: 1 start bit, 8 data bits, 1 stop bit! The UART controller was simulated and tested in hardware.
