An (f(x); m)-interleaved sequence Gong (IEE Trans. Inform. Theory 41(2) (1995) 400) over a !nite !eld Fq is a sequence where all its m-decimated sequences have f(x) as the common characteristic polynomial, which can be determined by a control parameter. This paper demonstrates how issues such as minimal polynomial, linear span, period and correlation values of an (f(x); m)-interleaved sequence ...

Typical mathematics instruction involves blocked practice across a set of conceptually similar problems. Interleaving, or practice across a set of conceptually dissimilar problems, improves learning and transfer by repeatedly reloading information and increasing discrimination of problem features. Similarly, comparing problems across different contexts highlights relevant and irrelevant knowled...

To significantly increase the sampling rate of an A/D converter (ADC), a time interleaved ADC system is a good option. The drawback of a time interleaved ADC system is that the ADCs are not exactly identical due to errors in the manufacturing process. This means that time, gain and offset mismatch errors are introduced in the ADC system. These errors cause distortion in the sampled signal. In t...

The use of frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can significantly improve the downlink bit error rate (BER) performances of DSand MCCDMA in a frequency-selective fading channel. However, the uplink BER performance degrades due to a strong multi-user interference (MUI). In this paper, we propose frequency-interleaved spread spectrum (SS) using M...

{In this paper, we propose a highly reliable RAID architecture called a Dual-Crosshatch Disk Array. It uses the proposed interleaved 2d-parity scheme, a low overhead triple-erasure correcting parity organization. It is a hybrid approach of RAID-4 and RAID-5 with one dedicated parity group and another parity group using block interleaved data and parity. The results obtained from simulations ind...

Calibration Techniques for Time-Interleaved SAR A/D Converters

In this paper, we study the beam-based training design jointly with the transmission design for the hybrid massive antenna single-user (SU) and multiple-user (MU) systems where outage probability is adopted as the performance measure. For SU systems, an interleaved training design is proposed where the feedback is concatenated with the training procedure to monitor the training status and to ha...

This document defines a new RTP payload format for the Forward Error Correction (FEC) that is generated by the 1-D interleaved parity code from a source media encapsulated in RTP. The 1-D interleaved parity code is a systematic code, where a number of repair symbols are generated from a set of source symbols and sent in a repair flow separate from the source flow that carries the source symbols...

A novel interleaved boost and buck converter with zero-voltage switching (ZVS) and zero-current switching (ZCS) characteristic is proposed in this paper. By using the interleaved approach, this topology not only decreases the current stress of the main circuit device but also reduces the ripple of the input current and output voltage. Moreover, by establishing the common soft-switching module, ...

Abstract. One-step iterative decoding for bit-interleaved coded QAM with conventional Gray mapping can give a significant improvement of performance for fading channels. Furthermore, iterative decoding with ideally known feed back bits is easier to analyze theoretically than non-iterative decoding. In this paper, we derive analytical expressions for the pairwise error probabilities for bit-inte...
