Referred to as INtervened-Timing, Enhanced-Rate Interval Modulation (INTERIM), the proposed technique is an isochronous pulse-based modulation technique, which embeds the telemetered symbol in the time interval between two consecutive ultrasonic tone bursts of different frequencies. To realize this idea, two pairs of ultrasonic transducers with different central frequencies and non-overlapping frequency responses are used. Each transducer pair oversees the transmission and receipt of one of the tone bursts. This is while using the same transducers in the same operational conditions (i.e., with the same excitatory-inhibitory pulse (EIP) excitations, same link medium, and at same distance), the INTERIM approach offered a maximum data rate of 500 kbps and 800 kbps at bit error rate (BER) of 1.4% and 6% respectively.Author owns copyright, except where explicitly noted.
