ABSTRACT:
A modulation apparatus for a cellular radio system in which capacity is increased and power consumption is minimized, said system covering large and small area cells of different sizes. At least two different modulation schemes are used in the system. For large area cells, constant envelope modulation is used for minimizing power consumption, and for small area cells, linear modulation is used for minimizing the channel spacing, and in this manner, for increasing the cellular capacity.
