Abstract:

Link-16 is the designation of a tactical data link that is being introduced into operations of the United States Navy, the Joint Services, and forces of the North Atlantic Treaty Organization NATO. Link-16 does not significantly change the basic concepts of tactical data link information exchange, but rather provides certain technical and operational improvements to existing tactical data link capabilities. The communication terminal of Link-16 is called the Joint Tactical Information Distribution System JTIDS and features Reed-Solomon RS coding, symbol interleaving, cyclic code-shift keying CCSK for M-ary symbol modulation, minimum-shift keying MSK for chip modulation and combined frequency-hopping FH and direct sequence spread spectrum DSSS for transmission security. In this thesis, we investigate the performance of a Link-16JTIDS-type waveform in both additive white Gaussian noise AWGN and pulsed-noise interference PNI when an alternative error correction coding scheme for the physical layer waveform is employed. The performance obtained using the alternative error correction coding scheme is compared to that of the existing JTIDS waveform when the same assumptions have been made for both waveforms. Based on the analyses, we conclude that the proposed alternative Link-16JTIDS communication scheme performs better than the existing Link-16JTIDS waveform in both AWGN and PNI for both coherent and noncoherent demodulation in terms of both required signal power and throughput.
