We describe new methods that solve wellknown problems associated with high throughput, robust communication in underwater environments. By robust, we imply simultaneous increases in enabled underwater communication data rates, range, and reliability. Our methods borrow concepts from advanced multi-carrier modulation using Orthogonal Frequency Division Multiplexing (OFDM), multiple input multiple output (MIMO) space time codes (e.g. Alamouti diversity), and zero carrier frequency ultra wideband
