| Popis: | 88 The software radio architecture has extended the digital realm into the intermediate frequency (IF) signal processing functions, such as band-selective filtering and up/down frequency conversion. In this thesis, the fundamental architecture of digital up converter and digital down converter are discussed. A more efficient algorithm for the practical implementation of multi-channel digital up/down converter is deduced under the pre-requisite of a low computation load. The converter contains two modules including the Frequency Shifting Interpolation Module (FSI) and the Frequency Shifting Decimation Module (FSD). These modules are implemented using Field Programmable Gate Array (FPGA). In final, to significantly reduce the requirements of logic gates, the pipeline FIR filter is exploited. |
