: The maximum excess delay of the channel model is given
: by τN = N*Δτ. Therefore, for τN =100μs, and N=64
: we obtain Δτ =1.5625 μs . The maximum bandwidth that
: the SMRCIM model can accurately represent is equal to
: 1 / (2*Δτ) = 0.32 MHz <=== Why
: 為什麼 The maximum bandwidth 是這樣算的呢 ?
: 看不懂....
就是取樣定理 取樣頻率至少要是被取樣訊號頻率的兩倍
