In wireless communication and particularly in wireless underwater communication, mobile radio links usually exhibit severe multipath fading that yields Serious degradation in the link-to-Noise Ratio (SNR) and consequently leads to higher Bit Error Rate (BER). Fading compensations like increasing link budget margin or interleaving with channel coding are typically required to improve link quality; however, these techniques are designed relative to the worst-case channel conditions, which results in low channel utilization. Transmission power, determined with the proposed algorithm, has been proven to be an efficient approach to improve the link quality and increase the channel capacity. Shannon capacity of a channel defines its maximal possible rate of data transmission for an arbitrarily small BER without any delay or complexity constraints.
