1. INTRODUCTION
Challenges in developing high performance underwater acoustic
modems can be summarized as:
1. Lack of maturity in underwater acoustic communications
technology at all layers of the communication stack. This
stems in part from the complex and dynamic nature of the
underwater channel.
2. Spatially and temporally dynamic nature of the
underwater acoustic channel. Theoretically "high
performance" communications may not be achievable
using the largely channel-specific (channel-static)
processing techniques similar to those which have evolved
for radio frequency and optical communications.
3. Resources. Without the expectation that the processing
