چکیده انگلیسی
1-min rain rate is the key element to predict rain attenuation at a location precisely. However there is the limitation of 1-min rain rate availability in Malaysia for long term local measurement because rain rate statistics are commonly derived on the rain gauge recordings base with actual integration times of 10-min or longer. Therefore, conversion of available rain rate distributions with longer integration times to 1-min rain rate distributions is necessary. This paper proposes new set of coefficients to current ITU-R for Malaysia in order to improve the accuracy of conversion from 1-h to 1-min rain rate. From this study, the test shows the proposed set of coefficients performed better than Emiliani et al. (extension of ITU-R), Chebil and Rahman method in terms of accuracy. This study is important to provide more accurate regression coefficients to system designers when designing link margin.
