Abstract


R \u0026 D and design of wireless receiving and sending system to expand the market demand for wireless emergency communications . 336-344MHz wireless emergency communication open band , this band of electromagnetic waves with better diffraction properties . With this band combined with OFDM technology to send and receive wireless image signal , can solve the problem of the emergency communication system mobile image acquisition . In this paper, from the point of view of product performance and price reasonable selection of devices , optimization program . Combined with the design of the power amplifier , to improve power amplifier nonlinear method is proposed and studied . Local oscillator design , combined with the requirements of system metrics selected embedded VCO frequency synthesizer chip , lower costs , reduced volume , the product closer to the market . This paper studies the nonlinear distortion of the power amplifier predistortion processing to improve the program . Then , combining the PLL theory, describes a method for the design of the frequency synthesizer . Then , a detailed description of the 340MHz wireless receiving and sending system 's overall program as well as hardware circuit . Finally , this paper provides analysis and overall indicators of the system , and the wireless link . The research results show that the pre-distortion technology applications to improve the nonlinear distortion of the power amplifier , and the system 's overall indicators meet the design requirements , and achieved a stable and sound transmission in actual use .
