Interleaving data and effects [PDF]
Journal of Functional Programming, 2015 Abstract The study of programming with and reasoning about inductive datatypes such as lists and trees has benefited from the simple categorical principle of initial algebras. In initial algebra semantics, each inductive datatype is represented by an initial f -algebra for ...

Journal of Telecommunications and Information Technology, 2022 This paper investigates the design of a modified matrix interleaving algorithm as a way to improve the performance of turbo codes. This proposed solution, known as the matrix-dithered golden (MDG) interleaver, utilizes the characteristics of a matrix ...

Electronics Letters, 2022 In this letter, a fixed‐latency interleaver architecture is proposed for interleave division multiple access (IDMA) systems. The existing multi‐stage algebraic interleaver suffers from the high latency originated from a series of multipliers and adders ...

Turbo Code with Hybrid Interleaver in the Presence of Impulsive Noise
International Journal of Emerging Research in Engineering, Science, and Management, 2022 In this paper, a numerical density function of Impulsive symmetric α-stable (ISAS) noise was presented and simulated in the turbo coding environment. The ISAS noise has no closed-form expression, making it difficult to realize. The ISAS noise can be used

The Effect Of Constraint Length And Interleaver On The Performance Of Turbo Code [PDF]
Engineering and Technology Journal, 2010 This paper presents a class derived from convolutional code called turbo code. Theperformance of turbo code is investigated through examining the effect of different constraintlength, the effect of changing rate, and the effect of interleaver on the ...

The NLM interleaver design for IDMA system [PDF]
, 2012 International audienceThe choice of a "good" interleaver in IDMA systems must demonstrate that the interleavers do not "collide" and easy to generate.

Blind Interleaver Parameter Estimation From Scant Data
IEEE Access, 2020 A method for blind estimation of interleaver parameter was recently reported which made additional data from a limited amount of received data. However, the process of making additional data creates undesirable linearity which degrades estimation ...

Interleaver design for turbo codes [PDF]
, 1994 A new type of interleaver for rate 1/2 turbo codes is designed which allows each information bit to be associated with its own coded bit. In this way the correction capability of the code is uniformly distributed over all information bits.

Research on unequal error protection with punctured turbo codes in jpeg image transmission system [PDF]
Serbian Journal of Electrical Engineering, 2007 An investigation of Unequal Error Protection (UEP) methods applied to JPEG image transmission using turbo codes is presented. The JPEG image is partitioned into two groups, i.e., DC components and AC components according to their respective sensitivity ...

, 2006 The chapter describes principles, analysis, design, properties, and implementations of optical frequency (or wavelength) interleavers. The emphasis is on finite impulse response devices based on cascaded Mach-Zehnder-type filter elements with carefully designed coupling ratios, the so-called resonant couplers.
