And the system can send the signal in code division multiplexing mode in theory, so it has a certain expansion of capacity.

同时在理论上该系统支持基于码分复用模式的定位信号的发射，具有一定的扩展能力。

Because of the enormous fading of the optical signal in underwater laser communication, the capacity of the error-correcting code must be well enough.

由于水下通信信道对光信号的衰减极大，实际通信系统的编码应具有极强纠随机差错和纠突发差错的能力。
