Engaging students into their own learning of foundational genetics concepts through the 5E learning cycle and interleaving teaching techniques

Journal of Biological Education, 2019
Students in a mixed majors undergraduate microbiology class often struggle with basic genetics concepts, generating gaps in their overall understanding of genetics. This can be a result of employing the traditional block style of instruction that focuses

Analysis and design of interleaver sets for interleave-division multiplexing and related techniques

2008 5th International Symposium on Turbo Codes and Related Topics, 2008
Interleavers play a key role in interleave-division multiplexing (IDM), interleave-division multiple access (IDMA) and related techniques such as multi-layer IDMA (ML-IDMA). The separation of the information of different layers/users is achieved by interleaving. Only carefully designed interleaver sets lead to a good error performance. Interleaver sets

A self-calibration technique for time-interleaved pipeline ADCs

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
In this paper, an effective digital self-calibration method for time-interleaved parallel pipeline ADCs is presented. The method corrects errors of MDACs within the channel ADCs and compensates gain and offset mismatches between parallel channels. According to simulations, 14-bit accuracy can be achieved with 10-bit device matching.

Analysis of speechreading cues using an interleaved technique

Journal of Communication Disorders, 1979
A method of locating visible differences between “homophenous” phonemes has been developed. Alternating frames from two video recorded VCV utterances which differ only in the consonant are interleaved. The output contains odd frames of one utterance and even frames of the other.

Interleaving Techniques for W-CDMA Linear Equalization Receivers

2007 16th International Conference on Computer Communications and Networks, 2007
This paper focuses on the use of specific interleaving techniques for use in W-CDMA (wideband code division multiple access). The linear equalization algorithm usually performs a matrix inversion on a matrix with a high level of sparseness, and such sparseness shouldn't be compromised with the use of a random interleaver; specific interleaver designs ...

Frequency-interleaving technique for high-speed A/D conversion

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
This paper introduces a concept of analog-to-digital conversion for very high-speed applications. Like the time-interleaving conversion, this method uses different conventional ADCs (channels), which work in parallel, but the approach is different.

Frequency Interleaved CDMA - A New Multiple Access Technique

VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
In this paper, a new multiple access scheme called frequency interleaved code division multiple access (FI- CDMA) is proposed. The major novelty of this scheme is that it is able to benefit from the advantages of the well known multi-carrier code division multiple access (MC-CDMA) and to solve one of the major drawback encountered by OFDM-based ...

Combined application of interleaving and modulation techniques in multiconverter topology

2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008
This paper presents a theoretical study about the combined application of interleaving and switching frequency modulation (SFM) in parallel multiconverter topology. We study the spectrum of the equivalent noise generation pattern that represents the aggregate effect of the switching of the four converters we have considered.

An improved interleaver design technique for parallel concatenated convolutional codes

IEEE International Conference on Communications, 2003. ICC '03., 2004
This paper is aimed at the problem of designing optimized interleavers for parallel concatenated convolutional codes (PCCC) that satisfy several requirements simultaneously: 1) designing interleavers tailored to the constituent codes of the PCCC; 2) improving the distance spectra of the resulting turbo codes which dominate their asymptotic performance;
