Abstract

In order to improve the efficiency multi band OFDM wireless underwater communication, the software technology offers the ability to develop OFDM transceiver architecture and his performance by using an optimal modulation and coding schema. The field programmable gate array (FPGA) represents a solution to have flexible mapping that adjusts several types of modulation. This paper aims to specify a new generic model that supports all modulations required by underwater communication. In order of achieving high-speed data transmission, high data throughputs, and low ratio of errors over many of the underwater channels
