碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 95 === In the recent year, Orthogonal Frequency Division Multiplexing (OFDM) becomes the technique of the popular choice for the transmission. Because this technique can provide high data rate transmission within the bandwidth limit. Furthermore, in the multipath fading channel, it also have high performance by guard interval. Since the evolution of Digital Signal Processing, it has been used for many transmission systems such as DAB (digital audio broadcasting),DVB (digital video broadcasting), WLAN (wireless local area networking)…etc. Previously, most researches about the performance of the Digital Video Broadcasting-terrestrial (DVB-T) systems are studied in hardware scheme and simulate in the channel environments assumed by researchers. Only a few of researches are researched by software and in the real channel environments. We keep on researching the previous program of the lab about DVB-T receiver. We’ll change the method of interpolation to calculate more accurate channel coefficients. And we will consider the channel state information into the metric to get higher performance. And we‘ll propose some problems that we will solve in the future.
