“…The FEC coding schemes used herein are convolutional codes of (n, k, m) = (2,1,9) and (3,1,9) with generator polynomials [561;753] 8 and [575;623;727] 8 , respectively. Although superior performance can be obtained by using turbo-codes, the iterative and computationally intensive decoding process is difficult to implement under tactical mobile communications equipment size and power constraints.…”

“…It is widely accepted that on-board processing (OBP) payloads maximize signal integrity under critical channel impairment [1,2,3]; however, recovery of the baseband data aboard the satellite payload requires substantial signal processing and in turn, cost. As a result, partial signal processing dehop-rehop transponder (DRT) systems have been developed for use in tactical satellite communications as economical alternatives to fully regenerative on-board processing (OBP) architectures [4].…”

This paper presents a comparative performance assessment of slow frequency hopped, frequency division multiplexed waveforms through dehop-rehop partial processing and on-board processing satellite payloads under the effects of jamming. Towards application in tactical mobile satellite communications, the performances of convolutional coded symmetric differential phase shift keying (SDPSK) and 1-bit differential Gaussian minimum shift keying (GMSK) modems are examined under the influences of jamming. Uplink channel impairment is modeled as partial band noise jamming (PBNJ), and band multi-tone jamming (BMTJ) coupled with AWGN and the downlink channel is modeled as AWGN. The simulated results and comparative analysis provide designers with a reference and quantifiable measure of the difference between each satellite architecture's performance with respect to overall signal quality and antijamming (AJ) capabilities for each of the waveforms under study.
