| Abstract | The study of this work is to develop a new path loss model for urban outdoor coverage in CDMA system based on the empirical measurements collected in CDMA network in Kuala Lumpur (KL), Malaysia. The new path loss model is developed by comparing of the calculated path loss from measurements to the well-known path loss models such as Free Space pass loss model [1], Okumura's Model [2], Hata's Model [3] and Egli's Model [4]. The Okumura's Model was chosen as reference in new path loss model development based on the smallest mean relative error [5] to the measured path loss with up to 10.46%. A semi-empirical model is developed from Okumura and the collected measurements by regression fitting method. This semi-empirical model will be used as reference in the optimization process where Okumura's model will be optimized to achieve smallest mean relative error to the semi-empirical model. The mean relative error has been reduced from 3.50629% to 0.00009% in order to find out the new path loss model by multiply with variables A, B, C, D, E & F to Okumura's model. This newly optimized Okumura's model is named as Yihpey's Model which has proved that it has the smallest mean relative error 6.67% to the measurements data collected in validation process. This model is more reliable with higher accuracy compared to other model for path loss calculation in urban region of CDMA System in KL. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
