Underwater acoustic communication is a growing research area since it has many military and commercial applications. There are lots of difficulties in underwater acoustic communication such as surface reflection, multipath and fading. An FSK communication system is implemented on FPGA. The system is tested and verified in underwater environment. Surface reflections are the major problem encountered during these tests. The effects of surface reflections to the underwater communication are investigated in detail. It is showed that surface reflections cause bit errors by generating the intersymbol interference (ISI).
