Laser pulse code is an anti-jamming measures used in semi-active laser guided weapons. On account of the laser-guided signals adopting pulse coding mode and the weak signal processing  it need complex calculations in the frequency measurement process according to the laser pulse code signal time correlation to meet the request in optoelectronic countermeasures in semi-active laser guided weapons. To ensure accurately completing frequency measurement in a short time  it needed to carry out self-related process with the pulse arrival time series composed of pulse arrival time  calculate the signal repetition period  and then identify the letter type to achieve signal decoding from determining the time value  number and rank number in a signal cycle by Using CPLD and DSP for signal processing chip  designing a laser-guided signal frequency measurement in the pulse frequency measurement device  improving the signal processing capability through the appropriate software algorithms. In this article  we introduced the principle of frequency measurement of the device  described the hardware components of the device  the system works and software  analyzed the impact of some system factors on the accuracy of the measurement. The experimental results indicated that this system improve the accuracy of the measurement under the premise of volume  real-time  anti-interference  low power of the laser pulse frequency measuring device. The practicality of the design  reliability has been demonstrated from the experimental point of view.

In order to connect DSP which has synchronous serial ports to the devices implementing asynchronous communications protocol  a method to implement UART communications based on programmable logic device is proposed in the paper. In the proposed method  the core function of UART is integrated in CPLD with VHDL. Firstly  UART data frame format and operational principle of UART were introduced after reviewing some methods to realize UART. The methods to implement UART transmitter  UART receiver and baudrate generator using VHDL were illustrated in detail. Then pre-simulation and synthesize of VHDL program were executed. Finally  the test with bit error rate was carried out on physical system. Experimental results indicate that 75 percent of the GLB are used by UART  and the bit error rate is less than 109. The experiment was implemented utilizing the RS-422 protocol and the baudrate is 62.5kb/s. The proposed method can satisfy the system requirements of high integration  stabilization  low bit error rate  strong anti-jamming and low cost. 2011 IEEE.
