Upper and lower performance bounds for Block Data Transmission Systems

The paper presents an analysis of the Block Transmission System (BTS) that has recently been proposed for mobile channels. Decision boundaries and decision regions have been obtained for the Block Linear Equalizer and the Optimum Detector for the system. Expressions for the error probability for the two detection processes are obtained and these provide the lower and upper bounds to the performance of the BTS in the presence of additive white Gaussian noise. The performance of the BTS is compared with that of the conventional Linear Equalizer. It is shown that despite of the reduced transmission efficiency the performance of the block linear equalizer is comparable with that of the linear equalizer. Furthermore, the Block Transmission System possesses certain inherent advantages over systems using continuous transmission, which makes it suitable for use in mobile communication systems.
