Multicarrier Signal Processing And Realization Based On FPGA

With the development of wireless telecommunication, The band of the signal became more and more wide. So the traditional single carrier communication mode already cannot satisfy the requirement of the wireless environment for signal transmission. In order to get a reliable way of transmission. Multicarrier communication become more and more important. However, An important problem in multicarrier communication is the decline of peak-to-average power ratio(PAPR). It Seriously hindered the development of multicarrier communication. This paper studies the PAPR algorithm based on FPGA implementation. At the same time elaborated the baseband signal processing:mainly for the rate of data transformation and the realization of the baseband shaping filter. The main content of this paper is as follows:Described the background of multicarrier communication research and the PAPR technology.The advantages and disadvantages of all kinds of algorithms are analyzed in detail, combined with the existing implementation platform the complexity of the algorithm was analyzed.Introduced the hardware implementation architecture of filter. Expounds the efficient implementation structure based on FPGA. And introduces the engineering structure commonly used interpolation cascade filter.The realization of the various modules are introduced in detail. Including interface design, digital intermediate frequency modulation and demodulation, filter module, CFR module, etc.By ChipScop through step by step sampling signal of each part, analysis the performance of the algorithm.Summarize the paper. Giving some problems and the solutions when implement the program.
