Interleaving planning and execution is the practical alternative to the problem of planning off-line with large state spaces. While planning via symbolic model checking has been extensively studied for off-line planning, no framework for interleaving it with execution has been ever devised. In this paper, we extend planning via symbolic model checking with the ability of interleaving planning a...

There are several ways to use iterative decoding techniques with coded continuous phase modulation (CPM). This paper presents a method using parallel concatenation of convolutionally-coded CPM. All CPM schemes can be decomposed into a ring convolutional code and a memoryless signal mapper. This allows a properly designed convolutional code trellis to be combined with the CPM trellis, producing ...

Studying the impact of operations, such as intersection and interleaving, on the succinctness of regular expressions has recently received renewed attention [12–14]. In this paper, we study the succinctness of regular expressions (REs) extended with interleaving, intersection and counting operators. We show that in a translation from REs with interleaving to standard regular expressions a doubl...

Abstract In direct sequence code division multiple access (DS-CDMA), frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can be applied to exploit the channel frequency-selectivity and therefore achieves much improved bit error rate (BER) performance than using the conventional rake combining. Even if FDE is applied to DS-CDMA, however, the uplink BER perform...

Abstract In direct sequence code division multiple access (DS-CDMA) and multi-carrier (MC)-CDMA, frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can be applied to exploit the channel frequency-selectivity and to improve bit error rate (BER) performance. In MC-CDMA uplink, however, the BER performance significantly degrades due to strong multi-user interfe...

We present a new method to analyze the performance of Reed-Solomon codes for hybrid-ARQ over Rayleigh fading channels with imperfect interleaving. Using the asymptotic results of level crossings of the faded envelope, we characterize the packet error probability as a function of the Doppler frequency and mean signal-to-noise ratio (SNR). We then use the notion of equivalent Doppler frequency to...

111 www.ijeas.org  Abstract— This work is focused to carry out investigation of WDM Free Space Optical transmission when even and odd channels are orthogonally polarized. In this work 8 independent channels each having capacity of 1.56Gbps are transmitted over free space optical link of 15 kilometer at different beam divergence angles. Systems with and without polarization interleaving are com...

Interleaving is a process to rearrange code symbols so as to spread bursts of errors over multiple codewords that can be corrected by random error correction codes (ECCs). By converting bursts of errors into random-like errors, interleaving thus becomes an effective means to combat error bursts. In this paper, we focus on how to obtain effective interleaving schemes for 2-dimensional (2-D) arra...
