Abstract
The invention is a communication method with the equipment belonging to it and its aim is to increase the number of users in a network or cell. Data is transmitted by the method by using a combined CDMA/TDMA or TDMA/CDMA multiple use whereby complementary code sets (complete orthogonal codes or non-interacting codes) are used as spreading codes. In the applications of the method to existing or planned TDMA systems, a CDMA part is added to them, by which a spreading coded CDMA multiple access is used in every time slot of the TDMA frame, in said way, to increase the number of users. The described method does not require any power control methods, nor any multiple access interference cancelling methods to increase network or cell capacity.
