Reduction of Channel Effect in Underwater Wireless Communication by Using Pre-Equalizer and Zero Forcing Method

The use of wireless communication in underwater environments is growing ever more popular due to its many advantages over traditional cables. One common issue that can be encountered while using wireless communication in underwater settings is the effect of channel distortion from the effects of Doppler shift, noise and multipath. To reduce the effect of this distortion, a pre-equalizer can be used to modify the signal prior to its transmission. This equalizer can be tuned for the specific effects of the medium, and can be further amplified to counteract the effects of the channel on the signal. By using appropriate equalization, one can thus reduce the effect of the channel distortion, allowing for higher-quality communication and more reliable signal reception. Furthermore, the use of a pre-equalizer can be a cost-effective alternative to using more expensive methods, such as increasing transmitting power. In conclusion, pre-equalization can be an effective way of reducing the effects of channels in underwater wireless communication systems.
