Multi-level block permutation
Under weak and reasonable assumptions, mainly that data are exchangeable under the null hypothesis, permutation tests can provide exact control of false positives and allow the use of various non-standard statistics. There are, however, various common examples in which global exchangeability can be violated, including paired tests, tests that involve repeated measurements, tests in which subjec...
متن کاملMulti-stage Decoding for Multi-level Block Modulation Codes
In this paper, we investigate various types of multi-stage decoding for multi-level block modulation codes, in which the decoding of a component code at each stage can be either soft-decision or hard-decision, maximum likelihood or bounded-distance. Error performance of codes is analyzed for a memoryless additive channel based on various types of multi-stage decoding, and upper bounds on the pr...
متن کاملSorting a Permutation with Block Moves
We prove a lower and an upper bound on the number of block moves necessary to sort a permutation. We put our results in contrast with existing results on sorting by block transpositions, and raise some open questions.
متن کاملA Secure Block Permutation Image Steganography Algorithm
Steganography is the art of hiding confidential information (secret) within any media file (cover media) to produce an amalgamated secret-cover media called stego media, so that the secret cannot be recognized or recovered by unauthorized recipients. Many steganalysis techniques have been developed enabling recognition of the existence of secrets within stego media and recovering it. Therefore,...
متن کاملChapter I Permutation Operations in Block Ciphers
New and emerging applications can change the mix of operations commonly used within computer architectures. It is sometimes surprising when instruction-set architecture (ISA) innovations intended for one purpose are used for other (initially unintended) purposes. This chapter considers recent proposals for the processor support of families of bit-level permutations. From a processor architectur...
