摘要：

This paper deals with potential use of digital modulation techniques for broadcasting future digital TV. Theoretical aspects of digital modulation are presented, starting from QAM techniques to orthogonal frequency division and multiplexing (OFDM). Theoretical performances of OFDM are derived and extended to cross-polarisation systems. Two generations of OFDM modems are described in detail, and real measurements obtained using first generation modem are given, from field trial in France and test bed in USA.
