Description
Summary:碩士 === 國立交通大學 === 電信研究所 === 85 === Digital implementation of frequency division multiplexing is investigated withthe use of perfect reconstruction filter bank. The PR filter bank is shown tobe equivalent to a cross talk free trans-multiplexer with synthesis section as the multiplexing input and the analysis section as the de-multiplexing output. With such filter bank implementation, both the QAM multiplexing and the VSB multiplexing are simulated. The advantage of such digital implementation is that the bandwidth utilization can be maximized and the band assignment can beeasily achieved as the selection of the modulation interpolation filter.
