| Abstract(in English) | This paper presents code-diversity and partial correlation weight coefficient control techniques to suppress multiple access interference in DS/CSMA and investigates several calculation methods of weight coefficients to improve these performances. First, in code-diversity, it is shown an ordering assignment method and a decimation assignment method are superior to a variance emphasis method for anti-cross-correlation maximal ratio combining. Second, by using LMS algorithm, more improvement of BER can be obtained. Next, in partial correlation weight coefficient control techniques, it is shown a variance emphasis method is superior to an ordering assignment method and a decimation assignment method. Finally, by using LMS algorithm, the BER performance can be improved in similar to code-diversity. |
