码元传输速率
码元传输速率
-
对于给定的码元传输速率和行纠错码,电路的工作交错度可有信号的中值电平和多普勒展宽(或信号的中值衰落率)确定。
The operating interleaving degree can be determined by the medium level and Doppler spread ( or medium fading rate ) of signals .

非对称结构包括在发射端的各个具有发射功率不等、调制方式不同和码元传输速率不等。
The unsymmetrical structure has several categories , including the users have different transmit power , the modulation modes of users are different , and the symbol rates of users are unequal .
