| Abstract(in English) | Recently, digital wireless communication systems become very popular to use in portable devices. Low-energy system implementation is strongly required because of the battery restriction or the power source restriction. In this paper, we discuss the effectiveness of controlling the bitwidth of FFT(Fast Fourier Transformation) circuits in OFDM(Orthogonal Frequency Division Multiplexing) based digital wireless communication systems. We show the experimental results of trade-offs between BER(Bit Error Rate) and energy consumption by changing the bitwidths of butterfly modules in FFT. |
