High peak-to-average power ratio (PAPR) reduction is one of the major challenges in orthogonal frequency division multiple access (OFDMA) systems since last decades. High PAPR increases the complexity of analogue-to-digital (A/D) and digital-to-analogue (D/A) convertors and also reduces the efficiency of RF highpower-amplifier (HPA). In this paper, we present a new DiscreteHartley transform (DH...

In process algebras such as ACP, parallel processes are considered to be interleaved in an arbitrary way. In the case of multi-threading as found in contemporary programming languages, parallel processes are actually interleaved according to some interleaving strategy. Interleaving strategies are also known as process-scheduling policies. In many systems, for instance hardware/software systems,...

We consider error-correction over the Non-Binary Symmetric Channel (NBSC) which is a natural probabilistic extension of the Binary Symmetric Channel (BSC). We propose a new decoding algorithm for interleaved Reed-Solomon Codes that attempts to correct all “interleaved” codewords simultaneously. In particular, interleaved encoding gives rise to multi-dimensional curves and more specifically to a...

We study an approach to concurrent contractions, that is, to simultaneous contractions performed by multiple agents. Using ideas from the semantics of programming we adopt an interleaved approach to reason about concurrent contractions. Although many of the notions from the traditional G ardenfors approach transfer to this setting, our approach also forces us to depart from the Gardenfors fra...

Understanding how to make learning more efficient and effective is an important goal in behavioral neuroscience. The notion of "desirable difficulties" asserts that challenges for learners during study result in superior learning. One "desirable difficulty" that has a robust benefit on learning is contextual interference (CI), in which different tasks are practiced in an interleaved order rathe...

OFDMA is one of the promising candidates for wireless communication. In the subcarrier mapping, the two most important subcarrier mapping techniques namely Interleaved and Localized mapping techniques are being considered. OFDMA is a method that assigns different groups of subcarriers to different users. When an interleaved technique is implemented with OFDMA, it is known as interleaved OFDMA (...

Multiloop Interleaved Control (MIC) is proposed, and it is combined with conventional multiloop controland the interleaved pulsewidth modulation scheme. The averagebehavior of the interleaved three-level switch-mode rectifier(SMR) behaves similar to the conventional boost-type SMR eventhough two capacitor voltages are imbalanced. It implies thatconventional multiloop control can be applied to t...

Bandwidth efficient coding schemes employing bit interleaved coded modulation and low complexity multiple turbo codes are investigated. The BER performance of these designs is shown to be superior to bit interleaved coded modulation schemes using conventional turbo codes.
