Abstract  Abstract

The system and method are applicable in information signals using connection means by distributed spectrum. Pseudonoise series are generated in order to ensure orthogonality between the users so that total mutual interferences will be reduced which guarantees high capacities and improved connections. By means of the orthogonal pseudonoise codes mutual correlation is zero for a preset time interval as a result of which there is no interference between the orthogonal codes. In an alternative series of signals of distributed spectrum are fed for which a control synchronization and speech chanels are designed.
