Abstract -- This paper applies two timing estimators, the
Schmidl-Cox and Minn's timing estimation methods, to a
SIMO-OFDM system to find the starting point of the
FFT (fast Fourier transform) window. Two different
combination methods, maximal ratio combining (MRC)
and selection combining (SC) are used for the timing syn-
chronization processing with each of the two timing esti-
mators. It is shown that, when we adopt the Schmidl-Cox
method, MRC achieves a better performance than SC;
however, if we choose the Minn's approach, SC is the bet-
ter one.
