The Dolphin modem is a compact, inexpensive, high powered, general purpose underwater communications device. With the included digital modulation schemes (FH, M-ary PSK), the modem will accommodate relative speed of at least ± 5 kts (± 2.5 m/sec) at the standard 26 kHz carrier frequency, and provides tracking through all header and (multiple) cargo packets.
The high fidelity class D amplifier provides full amplitude waveform transmission for any modulation scheme. We are not limited to constant amplitude waveforms! No more worries about limited dynamic range at the receiver. The Dolphin modem provides over 128 dB of dynamic range in the ADC.
Dolphin Modem’s software is engineered to enable customization. The environment includes many common signal processing tools, such as fast correlation and convolution, FFTs, and data storage. Dolphin seamlessly interfaces to external processing tools such as Matlab or Python. Ask us about adding your own algorithms to Dolphin !
