“…One way to compensate for BER degradation in MFSK modulation due to channel fading is by using coding process. This paper will analyze the block coding (BC) for error control used in MFSK receivers such as interleaving, Reed Solomon BC [11][12][13], and Alamouti space-time block coding (STBC) [14]. Reed Solomon BC that will be used in conjunction with MFSK is non-binary, linear cyclic code RS (n, k).…”

This paper presents an analysis to multipath fading channel effects on the performance of multiple frequency shift keying (MFSK) modulation that used in mobile wireless communications. These effects take account of AWGN, Rayleigh, and Rician multipath fading environments. The analysis also includes the block coding (BC) in error control coding is used in MFSK receivers such as interleaving, Reed Solomon BC, and Alamouti space-time block coding (STBC). The performance analysis of these models is based on bit-error rate (BER) of uncoded and coded MFSK systems when such models operate under multipath fading channels. The simulation results show that an additional enhancement in BER performance and coding gain is gained by adding a space-time block coding to the combination of interleaving and RS coding compared with uncoded MFSK model but at expense of system complexity.

We are interested in a communication system that operates in the presence of an intelligent jammer, under stringent power constraints, but with flexible bandwidth constraints. We optimize some of the key elements in the transceiver design for low power consumption, and thus high complexity components of the system, such as matched filters (MF), forward error correction (FEC) that employs iterative decoders, coherent demodulators, and bandwidth-efficient modulation formats, are not feasible for this research. Rather, our system is designed using M -ary frequency shift keying (MFSK) with non-coherent detection and fast frequency hopping (FFH), optimized two-pole bandpass filters (BPF), and Reed-Solomon (RS) codes with hard-decision decoding. Among other things, we show that by properly optimizing the key parameters of the BPFs and RS codes, we can design the system to be significantly less complex than the MF system with a performance loss of less than 1.4 dB for most scenarios that we considered. Further, the 2-pole BPF system can actually outperform the corresponding MF system by up to 2.4 dB in the presence of multi-tone jamming.INDEX TERMS M -ary FSK, multipath fading, ultra-low power-consumption, non-coherent detection, low-complexity filtering, fast frequency-hopping, partial-band noise jamming, multi-tone jamming, Reed-Solomon codes.

“…The total jamming power P M is assumed to be distributed over Q equal-power jamming tones with each having a power of P J = P M /Q, and the equivalent one-sided PSD level is defined as N M = P M /W ss . The jammer is assumed to have the complete knowledge about the transmission system except it does not know the exact FH band to which the signal is hopped [3], [75]. The jamming strategy is to choose the number of jamming tones, Q, such that it can cause the worst-case system performance.…”

Interference suppression for fast frequency-hopped communication systems over fading channels

In this thesis, we consider interference suppression for fast frequency-hopped (FFH) communication systems over fading channels. Three types of interference, namely, partial-band noise jamming (PBNJ), multitone jamming (MTJ) and multiple-access interference (MAI), are of interest. To suppress the effect of PBNJ, we propose a maximum-likelihood (ML) receiver for frequency-selective Rayleigh-fading channels and derive the corresponding analytical bit-error rate (BER) expressions. We then focus on a more general frequency-selective Rician-fading channel, in which an optimum ML receiver structure is proposed. In addition, two suboptimum ML receivers and their corresponding analytical BER expressions are presented. Furthermore, the linear-combining and product-combining receivers are also investigated under the same channel conditions. To mitigate the composite effect of MTJ and PBNJ, we present analytical BER expressions for an ML receiver under frequency non-selective Rayleigh-fading channel conditions. Following that, frequency-selective Rayleigh-fading channels are considered. System performance of the linear-combining, product-combining and ML receivers is studied and compared. We then investigate the effects of timing and frequency offsets on system performance under frequency non-selective Ricianfading channel conditions. Numerical results show that the FFH system is very sensitive to the timing and frequency offsets. vii ATTENTION: The Singapore Copyright Act applies to the use of this document.

An optimum ML receiver and two suboptimum ML receivers, namely, the ML-A and ML-B receivers, are proposed for synchronous systems over frequency non-selective Rician-fading channels. Analytical BER expressions of these two proposed suboptimum ML receivers are presented. In addition, we study the system performance of the linear-combining, product-combining and clipper receivers, and compare their BER performance with the proposed optimum and two suboptimum ML receivers. Performance comparisons show that the proposed optimum ML receiver has the best BER performance,
