一般調和解析によるドップラーシフトの解析

抄録

Recently, the satellite broadcasting has been started with a lot of programs by digital method. Another systems of the digital broadcasting will be made a start near future. We have been studying digital terrestrial television systems using VHF and UHF bands. The radio link is very useful for mobile reception, but the received signal becomes worse caused by the reflected, diffracted and scattered waves from buildings. It is very important to clear the characteristics of the channel condition for mobile reception. In this paper, we describe the characteristics of the delayed waves analyzed with Doppler shift by using GHA (Generalized Harmonic Analysis).
