sg-ntu-dr.10356-390502023-07-04T15:25:07Z Bit-error rate performance of coherent FFH/FSK systems over partial-band noise jamming and AWGN channels Shivakumar Puranam Krishnamurthy. Teh Kah Chan School of Electrical and Electronic Engineering DRNTU::Engineering::Electrical and electronic engineering::Satellite telecommunication 75 p. In this thesis, the bit-error rate (BER) performance analysis of uncoded coherent fast frequency hopped (FFH) systems utilizing binary phase-shift-keying (BPSK) modulation under partial-band noise jamming (PBNJ) and additive white Gaussian noise (AWGN) will be extended to systems utilizing binary frequency-shift-keying (BFSK) modulation. Three diversity-combining receivers namely, the coherent maximum likelihood (ML), linear combining (LC) and hard-decision majority-vote (HDMV) are proposed for the coherent FFH/FSK systems. Moreover the performance analyses of the FFH/BFSK linear combining receiver and maximum likelihood receiver are extended from the non-fading AWGN channel to the case of frequency non-selective slowly fading channel, characterized by the Rayleigh probability density function. The BER expressions are derived and Matlab simulations performed to verify the analytical expressions. The effects of the PBNJ fraction, diversity level, signal-to-jamming ratio and signal-to-noise ratio on the BER performance of coherent FFH systems are analyzed.
