Abstract: Long Term Evolution (LTE) supports peak data rates in excess of 300 Mb/s. A good approach to achieve such rates is by parallelizing the required processing in turbo decoders. An interleaver is an important part of a turbo decoder. LTE uses the Quadratic Permutation Polynomial (QPP) interleaver, which makes it suitable for parallel decoding. In this paper, we propose an efficient architec
A novel low-complexity detection scheme is proposed for the multiple-input multiple-output (MIMO) single-carrier frequency division-multiple access (SC-FDMA) systems, which is suitable for ASIC implementations. The proposed detection scheme makes an initial estimate of the transmitted signal based on a minimum mean square error (MMSE) frequency domain equalizer (FDE) detector and finds symbols wit
Purpose – Supply chains evolve and change in size, shape and configuration, and in how they are coordinated, controlled and managed. Some supply chains are mature and relatively unchanging. Some are subject to significant change. New supply chains may emerge and evolve for a variety of reasons.The purpose of this paper is to examine the nature of supply chain evolution and address the question “Wh
Purpose – The purpose of this paper is to examine the value chain processes that represent the “black box” between supply logistics integration and competitive operational performance in firms. To realize this objective, the authors develop a research model which comprises a series of linkages from supply logistics integration to operational outcomes using Porter’s concept of value chain and the r
We investigate the relationship between product and supply chain architectures. Both products and supply chains can have modular as well as integral designs. We synthesize previous research on both product and supply chain architectures and explore this relationship in a multi-method study, including a survey of 82 manufacturing firms and a multiple-case study of ten products and their respective
In this paper, we propose a time-recursive multipitch estimation algorithm using a sparse reconstruction framework, assuming that only a few pitches from a large set of candidates are active at each time instant. The proposed algorithm does not require any training data, and instead utilizes a sparse recursive least-squares formulation augmented by an adaptive penalty term specifically designed to
Post Conflict Futures is an ongoing project, where displaced Syrian academics meet in Visioning Labs and a global scenario group to jointly reflect on possible future developments and to look for actionable leverage points to work proactively for sustainable transitions. The collective visioning aims to identify aspects that may be critical in strategies for sustainable post conflict reconstructio
