Abstract
Aspects of the subject disclosure may include, for example, receiving, by a receiver through a medium from a transmitter, signals over an acoustic channel, where the receiving over the acoustic channel utilizes a high center frequency and provides for a high data rate, and where the medium is a fluid or a semi-solid medium. The device can receive power from the transmitter over the acoustic channel. Other embodiments are disclosed.
Claims11
A method comprising:
- providing a system including a transmitter, a receiver, and a processor, wherein at least one of the transmitter and receiver is moving;
- generating, by the processor, Quadrature Amplitude Modulation (QAM) signals encoding data;
- transmitting, by transmitter, the QAM signals over an acoustic channel through a medium to the receiver, wherein the transmitting over the acoustic channel utilizes acoustic waves having a center frequency of at least 2 MHz and provides for a data rate above 1 Mbps;
- receiving, by the receiver, the transmitted signals over the acoustic channel, wherein the received signals include Doppler distortion caused by relative motion between the transmitter and the receiver;
- and
- processing by the processor, the received signals using a second-order recursive learning algorithm for estimating arrival time to compensate for the Doppler distortion so that the data can be extracted from the received signals.
