“…The time interval between element, character and word is set as 0.1, 0.2 and 0.5 s respectivel The code length is based on the frequency of the occurrence of a particular character in the Englis language. The frequency of occurrence of English characters are extracted from [38] which is base on high samples of English words. The higher frequency alphabets get shorter sequences wherea code length is increased as the frequency of occurrence is decreased.…”

Bionic Morse Coding Mimicking Humpback Whale Song for Covert Underwater Communication

A novel method of bionic Morse coding mimicking humpback whale vocal is presented for covert underwater acoustic communication. The complex humpback whale song is translated as bionic Morse codes based on information entropy. The communication signal is made akin to the natural singing of male humpback whales. The intruder can detect the signal but will not be able to recognize the communication signal due to unified resemblance with the natural sound. This novel technique gives an excellent low probability of recognition characteristics. A flawless stealthy underwater acoustic communication has been established which has negligible chances of deciphered with high imperceptibility. Standard mimicry Morse codes have been developed for the characters of the English language and compared with Morse coding. Covert information of one character per second can be watermarked with perfect stealth and clandestine communication. This novel concept has been verified at transmission distance of five km and less than 10−3 Bit Error Rate (BER) is achieved at Signal to Noise Ratio (SNR) down to negative seven dB. Zero BER is attained by estimating the channel by a matching pursuit algorithm and equalizing the errors by virtual time reversal mirror technique.

“…If the polynomial count is within a certain range, then the character label corresponding to that range is the result of the identification and evaluation of the polynomial need not be continued. To test the capability of the identification technique, we used the frequency of the occurrence of letters in Indonesian, Malay, and English documents from Shah et al [28]. Figure 5 shows that the use of a double-track approach provides a smaller percentage of computed computations compared to a single-track approach.…”

Defining the process of type IRIS (Increasing Reward with Increasing Service) is one effort to get around the limitations of time available for execution. In this paper, the Double-Track Most Significant Operation First (DT-MSOF) strategy is proposed to improve system efficiency. In this strategy, the order of execution of the computing element according to their importance and the execution need only be done until the result is correct and/or acceptable. To know the performance of this strategy, two simulations are performed and an example of application is demonstrated. The simulation results show that the execution efficiency using DT-MSOF is better than DT-LSOF and DT-RSOF, measured by the percentage of executed computation. The demonstration indicates the possibility of implementation of this strategy on particular problem.
