This paper is concerned with the mathematical analysis for the sampling-based metric calculation for turbo decoding of noncoherent BFSK (NCBFSK) in additive white Gaussian noise (AWGN) channels, towards application in tactical applications. It is known that for NCBFSK, two decision statistics having Rician and Rayleigh characteristics must be accounted for in the decoding process. Therefore, this...
In this paper, SDPSK and 1-bit differential-detected GMSK are proposed for use in a tactical FH-FDMA on-board processing (OBP) satellite communication system. The proposed waveforms are modeled and their respective error performances are simulated under the effects of jamming. Both waveforms, known to be relatively robust for ACI and ISI, are convolutionally encoded and Fast Frequency Hopped (FFH)...
The built-in diversity of the fast frequency hopped spread spectrum communication system can provide inherent protection against interference for the multimedia data transmission for tactical use. Additionally, FEC coding can greatly enhance the system performance. However, care must be taken toward optimum performance in a power limited system. In this paper, effect of diversity L is observed with/without...
