在帶寬嚴重受限的水聲通道中實現高數據率通信，必須使用高帶寬利用率調制技術，並結合自適應均衡等技術以有效地克服通道多途傳播產生的符號間干擾。 -
Based on the facts that time of arrival ( toa ) of the first multipath signal is always most close to that of los propagation and angle of arrival ( aoa ) of the first multipath signal is not always most close to that of los propagation among all multipath signals in nlos propagation environment, a location algorithm is proposed to mitigate the influence of nlos propagation, which effectively reduces the feasible region of a ms in macrocells
依據在非視距傳播環境下存在的以下兩個事實：第一，最先到達多徑信號的波達時間總是最接近直達波的波達時間。第二，最先到達多徑信號的波達方向並不一定最接近直達波方向。針對宏蜂窩系統，從有效減小移動臺可行域的角度，提出了一種減輕非視距影響的定位演算法。 -
