Sliding block codes are an intriguing alternative to the block codes used in the development of classical information theory. The fundamental analytical problem associated with the use of a sliding block code (SBC) for source encoding with respect to a fidelity criterion is that of determining the entropy of the coder output.

For coherent detection, block-coded modulation is a bandwidth efficient scheme. In this paper, we propose theorems about the error performance of block-coded modulation using M-ary phase-shift keying (MPSK) for noncoherent detection. Based on these theorems, we propose a novel block-coded modulation scheme for noncoherent detection called noncoherent ...

Block codes for statistical synchronization
IEEE Transactions on Information Theory, 1970The performance of a class of block codes with unbounded synchronization delay, though finite average synchronization delay, is analyzed. Basically the synchronizer inspects the code symbol stream for the first occurrence of one of a set of sequences that appear in only one timing position relative to true sync.

Coding in the Block-Erasure Channel
IEEE Transactions on Information Theory, 2006In this correspondence, we study an M-ary block-erasure channel with B blocks, where with probability epsi a block of L coded symbols is erased. The behavior of the error probability of coded systems over such channels is studied, and we show that, if the code is diversity-wise maximum-distance separable, its word error probability is equal to the ...

Noncoherent block coded modulation
2003 IEEE Wireless Communications and Networking, 2003. WCNC 2003., 2004For coherent detection, block coded modulation with multistage decoding is a bandwidth efficient coded modulation system. In this paper, a novel block coded modulation system for noncoherent detection called noncoherent block coded modulation (NBCM) is proposed. We present a theorem for the distance property of the NBCM.

Minimal trellises for block codes
IEEE Transactions on Information Theory, 1988Basic concepts in the study of trellises of block codes are defined. It is shown that minimal proper trellises exist for all block codes. Bounds on the sizes of such trellises are established. These bounds are shown to be exact for maximum distance separable codes and nearly so for perfect codes.

The traditional Shannon theory focuses almost exclusively on block coding techniques, that is, source and channel codes that consist of mapping blocks of nonoverlapping data into blocks of encoded data. Such codes (1) have undesirable probabilistic properties such as loss of stationarity and ergodicity, (2) do not include several practical ...
