| dc.description.abstract | Detection methods for distorted digital signals using Linear Transversal Equalizer (l TE) have been widely studied. An even better tolerance to noise is achieved through the use of more sophisticated detection processes, which do not equalize the channel directly. Many of these processes, however, involve considerable equipment complexity. The purpose of the research is to develop effective methods for combating Intersymbol Interference (lSI) arising in digital data transmission over time dispersive channel. The technique that has been employed in this research is called Block Data Transmission System (BOTS). The system is a synchronous serial data transmission system and employs transmission of alternating blocks of data and zero level symbols. In contrast to the recursive symbol-by-symbol detection, each data block here is detected as a unit. The proposed study aims at the design of Block Linear Equalizer (BlE) for the Block Data Transmission System (BOTS). The performance of the BlE in the presence of noise and distortion are evaluated and compared with that of the minimum mean square error linear transversal equalizer. The results of the comparison show that:- 1. BlE can effectively remove distortion for all types of channels either with or without spectral null. 2. BlE reduce the data loss caused by unfortunate combination of the channel impulse response and the transmitted data sequence. 3. BlE performs exact channel equalization. The BLE is implemented using the point Gauss-Seidel Iterative Algorithm that consists of a sequence of identical or similar operations, which are carried out using a simple piece of equipment. This equipment can be further simplified to reduce the complexity. The use of the Gauss-Seidel Algorithm greatly simplifies the practical realization of the detection process and considerably reduces the complexity of the detector. Both aspects of using parallel and serial implementation have been considered. | en_US |
