Suatu graf dikatakan suatu graf jumlah jika terdapat suatu pemetaan satu-satu yang disebut pelabelan jumlah, dari ke himpunan bilangan bulat positif sedemikian sehingga untuk jika dan hanya jika , dimana . Untuk selanjutnya disebut simpul bekerja. Graf terhubung akan membutuhkan beberapa tambahan simpul terisolasi agar memenuhi aturan pelabelan jumlah. Graf jumlah dikatakan graf jumlah eksklusif jika tidak ada simpul bekerja pada graf . Banyak simpul terisolasi minimal sehingga pelabelan jumlah memenuhi pelabelan jumlah eksklusif disebut bilangan jumlah eksklusif, dinotasikan dengan . Suatu pelabelan jumlah eksklusif pada disebut optimal jika . Pada skripsi ini akan ditunjukkan bilangan jumlah eksklusif yang optimal dari graf matahari dengan . Graf korona dengan . Graf hairycycle dengan untuk genap dan dan , dimana menyatakan banyaknya simpul daun yang terhubung pada simpul ke- pada lingkaran. ...... A Graph is called a sum graph if there exist an injective labeling called sum labeling, from to a set of positive integers such that if and only if where . A vertex is called a working vertex. Any connected graph will require some additional isolated vertices in order to be sum labeled. Sum graph is said to be exclusive sum graph if contain no working vertex. The smallest number of isolated vertices such that sum labeling is an exclusive sum labeling called exclusive sum number, denoted by In this skripsi, it will be showed optimum exclusive sum number of sun graphs which is corona graphs which is , hairycycle graphs which is for even , , and , where is a number of leaves attached to the -th cycle?s vertex.

This book investigates the permutation polynomial (PP) based interleavers for turbo codes, including all the main theoretical and practical findings related to topics such as full coefficient conditions for PPs up to fifth; the number of all true different PPs up to fifth degree; the number of true different PPs under Zhao and Fan sufficient conditions, for any degree (with direct formulas or with a simple algorithm); parallel decoding of turbo codes using PP interleavers by butterfly networks; upper bounds of the minimum distance for turbo codes with PP interleavers; specific methods to design and find PP interleavers with good bit/frame error rate (BER/FER) performance. The theoretical results are explained in great detail to enhance readers’ understanding. The book is intended for engineers in the telecommunications field, but the chapters dealing with the PP coefficient conditions and with the number of PP are of interest to mathematicians working in the field.
