| Abstract: | The paper employs the fixed-length digital pulse interval modulation (FDPIM) as a method to achieve a modem for ultraviolet communication system, by comparing power efficiency, bit error rate, bandwidth efficiency and complex degree of circuit implementation. The modem is designed based on XILINX XC4VSX35 FPGA. The realization process of the modem is introduced in detail in the paper. The Modelsim simulation results can prove the design right. |
