Sequency majority multiplexing and concatenated sequency majority multiplexing are binary digital signal multiplexing schemes using sequency diversity instead of the conventional time or frequency diversity. These sequency majority multiplexing schemes exhibit some attractive transmission error recovery abilities when their channel multiplexing capacity is not fully utilised. This paper presents performance analysis and simulation studies of the sequency majority multiplexing and the concatenated sequency majority multiplexing in the additive white Gaussian noise and frequency non-selective flat fading narrowband channels. From these analysis, we proposed a novel approach to synchronous narrowband digital spread spectrum communication systems utilising, the concatenated sequency majority multiplexing scheme together with direct sequence spread spectrum multiple access. In this paper, some theoretical and experimental results are presented for our proposed synchronous narrowband digital spread spectrum scheme with the binary phase shift keying (BPSK) channel modulation technique. The proposed scheme shows promising performance gains and thus it is an attractive candidate for synchronous narrowband digital spread spectrum communication systems in the indoor wireless environment.","PeriodicalId":302569,"journal":{"name":"ISSPA '99.

This paper puts its emphasis on a few data and incomplete information to build the predictive system, excavates the connotative essence of a signal from the GM (1,1) predictor and refers to anomalistic (over predictive error) conditions to build the neural tuner database. So in the forecasting model the GM (1,1) model system predictive value will be appreciably modified while the anomalistic condition occurs. Simulation in well-known Mackey-Glass time series is presented to demonstrate the performance of the proposed predictive system.","PeriodicalId":302569,"journal":{"name":"ISSPA '99.

No direct single parameter is available which gives the quantitative measure of the effect of compression on the strength of edges in a selected region. Here, a new parameter called the frequency capture function (FCF) has been proposed to measure the performance of a compression technique in terms of the impact on the edge strength in a selected region of the image. We have used this parameter to compare the performances of JPEG, wavelet based set partitioning in hierarchical trees (SPIHT) and adaptive differential pulse code modulation (ADPCM) compression techniques for a test image. Results obtained are in agreement with visual quality evaluation of the images compressed and reconstructed with these techniques.","PeriodicalId":302569,"journal":{"name":"ISSPA '99.
