48^F推freeflying: 其實很單純從SNR考慮就好，64QAM調變複雜度較高，所以07/28 12:49

49^F→freeflying: 所需的SNR也較高，而越接近基地台的SNR就是會比較高07/28 12:49

50^F→freeflying: 的狀況下，自然會切換到64QAM來獲得比較高的網路傳輸07/28 12:49

51^F→freeflying: 率。07/28 12:49

52^F→freeflying: 可以體會原po的心情啦，今年的確是考了很多教科書沒07/28 12:53

162^F→freeflying: 有暗示了“單位”07/30 12:02

164^F推freeflying: 另一題沒記錯是問WCDMA的chip rate，我只對3.84M這個07/30 12:05

165^F→freeflying: 有印象...07/30 12:05

182^F推freeflying: 連其他考試的考古題都看，真的猛，超勵志07/30 22:58
