Description: The software phase-locked loop has got rid of the analog phase-locked loop and the digital phase-locked loop Complex hardware circuit design and device nonlinearity for tracking accuracy It has the advantages of simple structure and flexible parameter design. Using soft The software phase-locked loop is better than the hardware phase-locked loop It has better flexibility and versatility. Table of computer simulation results It is shown that the software phase-locked loop has better acquisition and tracking accuracy. along with With the development of software radio, especially the development of virtual radio, the development of software radio is becoming more and more important The application range of software PLL with high speed and high precision will be wider and wider.

Description: In this paper, an OFDM system based on IFFT / FFT algorithm and 802.11a standard is designed and simulated on computer. The emphasis is on the design and Simulation of OFDM system. In this part, the influence of the technology used in each link of the system on the system performance is introduced in detail. In the simulation process, the OFDM signal is modulated by QPSK and transmitted in AWGN channel. Finally, the bit error rate is obtained after demodulation. The whole process is simulated in Matlab environment. The simulation results and performance of ODFM system are analyzed. The relationship between SNR and BER is obtained through simulation, which provides a lot of useful data for the specific implementation of the system.
