| Summary: | The Doppler spread, or evenly, the mobile
speed of motion, is an evaluation of the spectral
spreading of mobile fading channel. A precise
estimation of the mobile speed and/or velocity is of great
significance in wireless mobile applications which needs
the acquaintance of the rate of the channel variations.
In this article we propose the use of the auto-correlation
of the in-phase component of the received signal to
estimate the maximum Doppler shift of the mobile
communication system. The proposed algorithm relies
on the zero crossing point of the auto-correlation
function of the in-phase part of the received signal. A
comparison between our proposed algorithm and the
algorithm proposed by Tevfik Yucek in term of the
Normalized Mean Square Error has been shown. |
