1. A method for receiving transmitted data through biological tissue using ultrasonic pulses comprising:
receiving, at a receiver, a request-to-transmit packet from a transmitter, the packet containing a ID of the transmitter;
measuring, at the receiver, an interference value;
sending, from the receiver, a clear-to-transmit packet to the transmitter comprising feedback data based on the interference value;
calculating a pseudorandom private time-hopping sequence and a pseudorandom private spreading code;
establishing a connection with the transmitter using the private time-hopping sequence and private spreading code;
receiving, at the receiver, a data packet from the transmitter using the private time-hopping sequence, the private spreading code;
measuring, at the receiver, an updated interference value; and
sending, from the receiver, an acknowledgement packet in response to the received data packet, the acknowledgement packet comprising updated feedback data based on the updated interference value.
