Abstract
The multiband communication technique is effective in terms of performance and throughput efficiency because it can overcome selective frequency fading by allocating the same data to different frequency bands in the environment of rapidly changing channel transfer characteristic. In addition, the transmission distance can be further extended while overcoming various underwater channel environments. In this paper, we analyzed the performance of multiband transmission technique in underwater communication by increasing number of band using Turbo pi code with a coding rate of 1/3. Simulation results shows that the performance is improved when the number of bands is increased based on the received SNR.
