数字电视地面广播系统中3780点IFFT算法的逻辑优化设计

The main task of this paper is to complete logic design and implementation of 3780-point IFFT algorithm of OFDM in the national standard for digital television terrestrial broadcasting system. To slove the higher error rate of the logic for the current design,analyzing the data characteristics in fixed-point format、block floating-point format and floating-point format,this paper presents four optimization program,and completed the design of the program logic.
