AbstructThis paper studies the coded performance of multichannel MFSK and DPSK signalings in mobile satellite environments characterized by various kinds of multipath fading. Rician, Riciadognormal, and a convex combination of Rician and Riciadognormal or RayleigMognormal distributions are used to model these communication channels. We investigate the minimum average signal-energy-to-noise rati...

Four self-organizing neural networks are compared for automatic deinterleaving of radar pulse streams in electronic warfare systems. The neural networks are the Fuzzy Adaptive Resonance Theory, Fuzzy Min-Max Clustering, Integrated Adaptive Fuzzy Clustering, and Self-Organizing Feature Mapping. Given the need for a clustering procedure that ooers both accurate results and computational eeciency,...

The timing structure of multiple successive radar pulses constructs a high-dimensional pattern for intercepted pulse trains, which is called as repetition interval (PRI) pattern. By treating the machine that uses differently permuted to communicate with surroundings, this acts grammatical its language. Compared discrete PRI set conventionally used train description, contains richer and more con...

Although low-density parity-check (LDPC) codes in modern communication standards have been extensively studied over a memoryless channel, their burst error correction capacity channels with memory has yet to be thoroughly analyzed. The conventional approach transmission uses interleaving within buffer of several codewords. However, such an reduces the efficiency redundancy embedded by error-cor...

In the modern electronic warfare signal environment, multiple radar signals of high density are mixed and received, separating them into for each emitter is an essential step identification. Each has its own pulse repetition interval (PRI), which a key parameter deinterleaving trains. The PRI modulated in various forms depending on purpose operation, analyzing mean modulation type core processi...

LoRa, as a representative of Low Power Wide Area Network technology, has attracted significant attention from both academia and industry. However, the current understanding LoRa is far complete, implementations have large performance gap in SNR packet reception rate. This article presents comprehensive physical layer protocol (PHY) reveals fundamental reasons for gap. We present first full-stac...

Radar signal sorting is the core part of electronic support measures, which responsible for deinterleaving overlapping pulse sequences received by receiver from complex environment, separating different radiation source signals, and providing identification. Particle swarm optimization (PSO) a population-based global algorithm with great advantages in intelligent can adapt to electromagnetic en...

The RADARs use complex techniques such as stagger PRI, jitter PRI with frequency agile characteristics. The frequency agile RADARs switch frequencies with in a pulse to get different types of advantages. Today lot of RADAR signal processing takes place on FPGA platform. These signal processing algorithms include pulse parameters estimation, deinterleaving of mixed pulse patterns, processing com...

It has been well established in the literature that the appropriate criterion for optimum trellis coded modulation design on the additive white Gaussian noise channel is maximization of the free Euclidean distance. We show here that when trellis coded modulation is used on a Rician fading channel with interleaving/deinterleaving, the design of the code for optimum performance is guided by other...
