Medium-access control schemes for ultrasonic communications in the body based on second order statistics
First Claim
1. A method for calculating a forward data generation rate and a forward transmission probability profile for communication through biological tissue using ultrasonic pulses, the method comprising:
- measuring, with a receiver, sets of interference values between the receiver and a transmitter, each set of interference values corresponding to one or more instants in a time slot on a communication channel;
calculating a first order moment and a second order moment for each instant based on the interference values corresponding to the measured instant;
calculating an outage probability value for each set; and
calculating the forward data generation rate and the forward transmission probability profile based on the calculated outage probability value and a predetermined threshold transmission rate, a predetermined transmission delay threshold, and a predetermined residual transmission error rate.

Abstract
Methods for ultrasonic communications through biological tissue using ultrasonic pulses are disclosed. For example, methods for calculating a forward data generation rate and a forward transmission probability profile for ultrasonic communications through biological material are disclosed. The method may comprise measuring sets interference values corresponding to instants on a communication channel. First and second order moments may be calculated for each instant based on the measured interference values. An outage probability may be calculated for each set and the forward data generation rate and forward transmission probability profile may be calculated based on the outage probability value and other parameters and a threshold transmission rate, a transmission delay threshold, and a residual transmission error rate.
