MEDIUM-ACCESS CONTROL SCHEMES FOR ULTRASONIC COMMUNICATIONS IN THE BODY BASED ON SECOND ORDER STATISTICS

摘要

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.
