Low-complexity block-constrained trellis coded quantization (BC-TCQ) structures are studied, and a predictive BC-TCQ encoding method is developed for quantization of line spectrum frequency (LSF) parameters for speech coding applications. The performance is compared with the linear predictive coding (LPC) vector quantizers used in the AMR-WB (ITU-G.722.2)(More)
In this paper, low-complexity block-constrained trellis coded quantization (BC-TCQ) structures are introduced, and a predictive BC-TCQ encoding method is developed for quantization of line spectrum frequencies (LSF) parameters for wideband speech coding applications. The performance is compared to the linear predictive coding (LPC) vector quantizers used in(More)
A new microcode-based BIST (built-in self test) circuitry for embedded memory components is proposed in this paper. The memory BIST implements march algorithms which are slightly modified by adopting degree of freedom concept to detect address decoder open faults on top of conventional stuck faults. Furthermore, it is shown that the BIST-modified march can(More)
This paper proposes a flexible encoding technique based on multi-stage multiple scale lattice vector quantization and block-constrained trellis coded vector quantization. It is used for the spectrum encoding, more precisely encoding of the LSF parameters, and incorporated in the recently standardized 3GPP EVS codec. The proposed method can handle multiple(More)
In recent years, the amount of data produced by mobile devices and the Internet has increased rapidly. To facilitate the storage of such a large amount of data, open-source-based cloud storage services have also increased. However, most of administration tools which are specialized in managing open-source-based storage services have shortcomings such as(More)
In this paper, a block-constrained trellis coded vector quantization (BC-TCVQ) algorithm is combined with an algebraic codebook to produce an algebraic trellis vector code (ATVC) to be used in ACELP coding. In ATVC, the set of allowed algebraic codebook pulse position is expanded, and the trellis branches are labeled with these subsets. Viterbi algorithm is(More)
